Nice composition, and I like the way the color details move your eye around the design, but it needs something else conceptually.
Maybe some interplay between the idea of the tree and the wooden furniture? Like maybe that the tree will become furniture or the other cabinets were once it's neighboring trees coming back to visit?
i like the colors and the way you incorporate the shirt color into the design. very nice concept as well.
right now my eye goes directly to the open cabinet toward the bottom left of the composition, that dark spot could be broken up a little... maybe you could make it more evident that the tree has drawers and doors by somehow merging the bottom cainet with the tree. (???)
