All in all not a bad first attempt, I remember mine (laugh). I think you need to add some moutains in the background a little farther back to give some depth perception, reduce the haze factor just a little, and add some clouds or something to the sky. Maybe also add some rocks, foliage, stumps, things like that to give a little more activity in the scene.. Good job and keep trying practice makes perfect, if there is such a thing in 3D.
