Water: You... you didn't even try. I suppose it's not
that bad, but there's a serious lack of shading on this, not to mention the lack of any texture on the head and spikes. Meh.
Camouflage: The pattern on this is well done, particularly the speckling on the underbelly, but the colors... The main green is is desperate need of desaturation; as it is, it's almost painful to look at. The wings clash a bit, though that might be just be because the body color is so painfully bright. The eyes really clash as well; I suppose they made them blue to make them pop, but it defeats the camouflage purpose and is just overall unpleasent. A dark green would have most likely been a better choice.
Tl;dr - The patterning is great, but this needs desaturated badly.
