Hi, everyone! Thanks for the great replies! Glad everyone is liking this piece…
bao - It’s not exactly a cover, it’s just aportfolio piece made to look like a cover. If you want book-cover jobs, it’s always good to demonstrate not only that you can paint well but that you understand the layout necessary for books, i.e. leaving blank spots for title, author’s name, etcetera. Specifically, this is designed to be a book for teens/tweens, and they tend to have pretty simple compositions with the main character(s) front and center, which is why I went for such a simple, symmetrical compsition, to try to look like one of those books.
LS Knight - Sounds like a great idea… I’m already onto a new piece, so you should get to work on it! (They key will be in conveying the point without anyone even needing to read the title.) Have fun!
Nick - Thanks so much, that means a lot, especially coming from an artist of such caliber as yourself - I really enjoyed your article on children’s book illustration a couple of issues back, which is of course exactly what this was intended to be, too. As for effortless… Ha! I need to stop falling in love with compositions that involve dozens of bad-guys! 
[plug] For those of you who haven’t seen the IFX article, it’s about my incredibly intensive and insane way of setting up dozens and dozens of layers in Photoshop to comp my colors. It lets me make dramatic palette changes rather late in the game before I flatten everything in order to get just the right (imho) color scheme. In the article, you can see pretty much this exact same painting with 5 completely different color schemes and compare them. Anyhow, if it sounds interesting, check it out! [/plug]
