Not a bad first-time foray into 3D art. I'm also rather impressed at how good the grass looks behind the bear. In general though, the lighting doesn't really illuminate the bear, the landscape could use more hills, the blade-of-grass model needs to be smoothed, and your textures need more detail. I don't mean to be discouraging: this is still a great stab at it, and you could with two hours work bring its quality up noticeably.
Keep it up!
