Could use a better composition. nice colors tho.

I'm not sure that a pole with lights coming off of it makes a "tree".

Thinking out side the square

Looks like a tree to me, but honestly I don't think that's the main issue. That bright light takes so much off the focus (the light tree) I can't tell what it is to the right of it because thereand I would have at least leveled the base of the house.

I would suggest centering the tree at least.

Have to agree with Jawshoewhah, and the tree looks tilted little bit.

Light and noise needs improvement...

unfortunately the background light is so blow out (direct sunlight) it's killing the rest of the shot. Quick tip, always try to get your shot with your light source more behind you.
