Anyway—this week's painting is a tad more ambitious than the last couple of paintings, if only because it actually takes up an entire sheet of paper and I probably spent more time on the background than anything else.
As usual, I roughed out the drawing on the computer, traced it off and refined it on paper. I wasn't feeling too confident over what the color scheme and lighting would be, so I roughed that out in Photoshop as well.
And, as usual, I started painting with the tones and shading. After some time had passed it occurred to me that once again I had forgotten to do something vital: tape down the paper so it wouldn't warp.
Any tape will do as long as it isn't terribly sticky—you don't want the adhesive to damage the paper, for obvious reasons. The masking tape can also be useful for blocking out large areas of color that you don't want to run into the details of your picture.
The final product ended up coming out quite a bit different than I anticipated. I opted out of making the lower half of the background quite so dark, mostly because I liked the interplay of the reds and greens and didn't want to mute them.
Of course, there are still a few things here and there that could stand to be touched up. Sometimes it's good to distance yourself from your work for a day, so that when you go back to it you have a clearer vision of what you need to do with it.
