Android Phone Model and Render

Did this model for Run Studios. I have been waiting a few weeks to post this. The phone advertising just went live today, so now I can show it!! The modeling took me about 3 days done in Maya. This shot is lit with standard area lights. Rendered in Mental Ray with Final Gather, of course.

Here is my most recent digital painting in progress. Started Saturday morning and have been painting on it off and on. Have spent probably 5 hours total on it. I am following a step by step breakdown in a Bob Ross book called the "Joy of Painting." I think it's the 25th volume.

I am looking for critique on this piece. I am confused on how to get the tree foliage to work right. Also, the transition from the forground to the middleground and the middleground to the background has been very tough so far. Thanks!!
