Wow, looks very nice. Ashley Wood fan? (Who isnt,hehe)
I love this GD/Illo crossover.
Do I dare crit? I will, and hopefully you wont think less of me...
I say characterwise on the covers, some of them seem to be lacking something, the poses look a bit flyswatted.
Maybe pick up a book on animation, and check out the section on exaggeration, you know, taking the peak in a normal action line and just pushing it that little bit farther, so its not quite human motion anymore.
Also, some of the are a bit difficult to read (covers), there is so much happening in them, and my poor brain cant take it all in.
