I'll preface this, like many others, that I'm not a huge fan of dictating stars; I feel silly and pompous in doing so.

Whereas I cannot really critique your technique and tell you what is absolutely and concretely better, you will be receiving my personal opinion in full.

I find this piece to be very simple in essence, in comparison to other pieces I've seen from you. I thoroughly enjoy the drab color palette you've chosen; I think the burnt umbers, rusts and murky greens provide an interesting complement to the very vital symbolism that is a tree filled with leaves. Where many times this color palette, I've found, would reflect a bare or dying tree, you've elected to go the other way which changes the scope of things drastically.

I feel that the wispy bits are a little tacked on, and almost a little out of place. A bit like you were looking at the piece saying to yourself, "Hmm. Needs a like je ne sais quois" and stuck them on. I do like the simplicity of them; there isn't a big fandango of swirls and hallelujahs, but at the same time, I wonder if the piece wouldn't stand alone if they were a little dimmer, or not there at all? That may just be taste, though.

I enjoy how the vertical patterning in the "ground" complements the horizontal sweeping of the "sky". I also very much like the asymmetry of not splitting the canvas precisely in half. It creates a bit of, what I think is, desired tension, to keep the eye interested. Again, this may be a matter of taste, but I think that the piece might benefit from this slanted ground being a little higher or a little lower. I think that despite the slant provided to break it up, it could be more dynamic by lessening the near 50/50 break to about a 60/40 on either end.

I hope this makes sense. All in all a very pretty and soothing piece.
