I must say,I think I've done very well. Oh,and the streaks of light are because the trees leave a few gaps that let light in. I made the butterfly glow just for fun 
I did some shading,too. And the mouse is taking da cheeese. 
I thought the eye was too bright compared to the other colors so I used air brush with black to darken it. Oh,and there ARE butterflies that big. Maybe even bigger! 
Well,I hope it's good enough to win.Enjoy!
