Right off the bat, I already have a picture painted in my mind of what the full scene looks like. The trees are well made, I enjoy the use of shading and the shape of the trees being quite unique. There are, however, a few problems I have with the picture. One such problem is that I cannot tell if the trees at the bottom of the picture are separate from the ones at the top or if they are closer than the upper trees. Another problem I have is that I am unsure what is above the bottom trees. I assume that it's water which would fit well with the picture, yet I don't know for sure. Unfortunately, the piece's theme has been conveyed before in various settings and the piece does not leave me with a lasting impact.
Overall, I do like the piece and understand what it conveys. I do think more should have been added, but it's a good drawing. I only think some aspects should have been tweaked and some more foliage should have been added. Other than those points, it's quite well-drawn. Keep it up!
