Seeking ligth and shadows critique

[nickzornart]

I'm noticing a couple of things: the background looks like it's very hazy, almost foggy, but the trees in the fore and midground on the right, as well as dinodude, have very sharp shadows, with the light very obviously coming from the right as well (except for dinodude's thorax area, that looks like the light is coming from directly above). If it's foggy, there won't be those sharp shadows. If there are those shadows, then the sky should be pretty clear, with nothing diffusing the light through the atmosphere. Also, if the light is coming from the right with that much intensity, I would think that there would be more of a shadow moving off from the dinosaur to the left.

Also, the tree directly behind dinodude's head looks to be in about the same value range as the tree at the left edge, which is on the opposite bank of the river. This messes with the eye.

All in all it's a good start though.
