Re: It's an order, RACE!
This is a nice concept and is well executed. That being said, there are some flaws that do make it feel, as other people have noted, incomplete.
The first thing that I noticed, is that there seems to be an inconsistency to the level of detail that the animals are at. Some of them, most noticeably the dragon and the tiger, have a fair amount of detail to them. Many of the rest seem to be plain and somewhat indistinct by comparison. Specifically, the monkey's lack of detail makes it difficult to tell what it is. You might consider adding some more detail to the monkey's head to make it more apparent that it is a monkey.
The snake is inconsistent enough, that it almost seems like it was tacked on as an afterthought. Most of the other animals have at least three levels of shading, whereas the snake only has two. Also, the line thickness on it seems very thin compared with the rest of the animals. I think if you thicken up the lines around the snake, and added another level of shadows to it, it would give it more of a finished look and help unify it with the rest of the animals.
Also, the snake doesn't lend itself well to the flow of the piece. When you look at the piece, your eye starts up at the top-left corner and flows around to the right and down, in a nice loop... until it gets to the snake. The snake's head leads the eye down and away from the remaining animals. This gives the impression to the viewer that the five animals in the front are separated from the six animals in the back. If you point its head more to the left, it will help bring the flow back in line with the rest of the composition.
There is also a large dead space in the middle which, coupled with the snake, creates a very distinct line through the piece that breaks up, what is otherwise, a very good composition. You should consider possibly drawing in some of the horse's back into that space, to help break it up and give it a more coherent feel. Additionally, it would help that spot taper into the dragon more.
This design shows real promise, and I think with just some minor tweaks, it could be a really amazing piece.
As always, these are all just suggestions. This is your piece, and you are free to do as you like with it. If it prints, you can ignore everything I say because obviously nobody else cares about the imperfections I pointed out. That being said, I do encourage you to play with the image some more regardless. I like to see a piece with promise reach its full potential.
