The intricacy and detail of your background is gorgeous. All of the leaves and trees are defined and given their own special touch. The little bit of blue is enchanting and beckons the audience to wonder what secret mysteries lay within.

The figure is beautiful. His light skin stands out from the background magnificently, and the attention to detail in each of his muscles is as delicate as the forest behind him. I especially love the realism you've captured in his eyes and facial expression.

On the constructive side of this Critique, his head appears a little too far forward, almost stiff. You might consider using more colour in his skin (esp. the shadows), to help him blend more easily with his background.

Fantastic work as usual!
