I will be definitely studying these trees next time I draw forest 
Great work!
It's no easy task to paint so many trees.Love the color of your sky.
That is indeed a lot of trees. 
It seems to me that the pine trees near the ominous reaper character should be noticeably bigger than the ones near the mansion and further, though. Especially since the leafy trees next to him are so much bigger than the pine trees right behind.
@Wayuki: You're totally right, thanks!
