Silly list with obscure doodles made me think to do this. Maybe shed some light on the great mystery of how I make big crazy pictures of stuff. How I angst over it, and plan, and over plan, and get hung up, and waste time and....well you know...if you want to keep thinking its magic instead of smoke and mirrors, just move along and skip this post ;-)
I start out with concepts and a mental image - sometimes very clear sometimes vague. Don't be fooled - a lot of times the clear ones are the most frustrating to produce. In this case, I knew I wanted to do two posters, and I wanted them to fit the theme for the show they would be in - which is 20,000 Leagues Under the Sea. I thought about it and sketched now and then to try to clarify the ideas - usually while I'm out doing something else so most of them end up in my pocket moleskin.
Usually this means a page or two of blocky layouts and vague concepts. For the first poster I was sure I wanted a submarine, and to use rays of light from the surface as a framing effect on the submarine. I couldn't decide if there should be a robot diver or not - and the original concept was a cruise advertisement. Once I think long enough, usually the concept becomes clearer. Then I do..more tiny blocky layout thumbnails that no one can understand but me. Like...the two from that list!
The second poster was one of those that came to me all at once, pretty clearly. No prep work there, just one thumbnail and yes I know that's how it should be. Now THAT poster is the cruise advert, and the first poster has become a national park style poster. Still totally not sure about the robot diver, but the rest is pretty clear.
Now I need to tighten up the layouts, clarify what's actually going into the images, and because these are going to be big poster painted style posters, I wanted to work out limited color palettes. So I jumped straight to the color thumbnails. I used to do a whole lot of sketching before this step but honestly - I really just enjoy painting these little thumbnails so much that I jump right to them especially if I'm grumpy or stuck for any reason.
While I was starting these, I suddenly realized that the national park poster had a theme, and it was the deep trenches (even though the light rays and ocean surface along with the deep sea fish would never be visible together its just TO GOOD to pass up. I fought with myself about this, seriously, but...ANGLER FISH and lights and ....its just to good). I actually did multiple versions of the colors for the second thumbnail, which is why its rougher and more scribbly. The first few just didn't work. So I fell back on my favorite orange/blue set. I admit, these thumbnails make me happy - and at this point I'm pretty excited about both ideas. Don't worry this stage of being very pleased with myself will end very shortly...
Now I do something that YOU SHOULD NOT DO. Seriously - its bad, don't draw this way. What you SHOULD do is work on a sketch of the entire image, bringing the full image tighter and tighter towards finish evenly over the full piece so you don't loose sight of the size and space relationships. But computers MAKE YOU LAZY. And for a long time now I admit I've just tossed this whole rule out the window and now I almost always draw pieces separately then piece them together. Usually its the character elements that I do piece by piece, then place them into the layout and add the tightened background around them. Shame on me. But its so much easier to focus JUST on the characters and to be able to get one right and shift them all back and forth and mess about with the scale. Sometimes I do this on paper then into the computer then I print and sketch on top of that and scan again and go back and forth. But right now for some reason computer sketching has been going well so I'm all digital so far.

I stick reference in the same file off to the side, in this case victorian facial hair and sailors uniforms ;-) If you look closely you can see, behind the sketch a very rough light layout sketch that has been completely ignored...The robot goes in that empty space between the two tables, but I haven't decided what kind of hat he will wear so...yeah he's off to the side. See what I mean about computers making you lazy? I should probably learn to be more decisive, but I don't HAVE TO because the computer lets me drag the robot about and put him where I want him.
Now that I look at him, I think the officers cap is a better silhouette...although the sailor hat is probably more ...job appropriate. Hmmm.
