Good things:First of all i love the feeling as i was looking at oil painting. Leaves are perfectly made, their colors (i mean their saturation changings) makes the work so good. Tree has nice details, that branches near top looks great. The background is perfectly made - things that are near man, a little bit above him. Bad things:the bottom of tree looks a litlle bit spider-like. The man on right do not fit there. Colours are no so good and details. I know that he is kinda in shadow, but it hurts my eyes how he looks. And the place he is standing at, also not well made.
But as longer as i am looking at the work i like it more and that first sight observations about bad things are going down and i see great masterpiece. (but first sight observations were like that, so i wrote them here)
I must say, i enjoy these mysterious ones. Good: I like the mystery surrounding it, the nice blue mist, as well as the colors of the leaves, and the tree. I also like the way you made the tree elevated, as if it were actually going to move. Bad: I like the man were he is, but the color should have been something that went along with the rest of the picture. Though I can see most of the picture, there are part were it begins to duplicate, or fade out.
In all it is a very interesting picture, the feel of it brings a bit of awe to me.
