Good for your first one, few comments, most have been addressed though. -Your grass is fine, it fits in nicely with the style of the water, which is nicely done. -Your tree needs some work though. Make it less shaded from light to dark on both sides and change the shape, I suggest looking at some reference pics. -Shark is good, but I didn't really know what it was, maybe make your light source from one specific side instead of straight up. -You don't need to use to much dither. It doesn't work so extensively on the tree and the shark. Other then those nit picky points, good piece so far.
