I know you've got another thread, but I think it'll be better to stick with this new one.
The best bit is the orange Castle Crasher, he's got a great cartoony style, and since he's got an arrow in the back of his head, I'm unsurprised that he's crying!
Overall I think the content of the pic is in the corners (crasher, bird, archer), which makes your pic look empty ... even though you've got a lot going on. It's a bit late now, but I would make the castle crasher bigger, giving him a bit more dominance in the pic.
You've also got a lot of different lineweights, especially with the archer, which makes it look like it doesn't belong in the same pic. Similar linewidths would provide a uniformity to the pic, bringing everything together.
