Experimentation and wood supports

Today I went at a large canvas that used to be a tree in a snowscape. I'd painted it a few years back and although some people liked it, I felt it was too stiff and modeled and didn't fit in with my other work. I re-worked it numerous times hoping something cool would emerge but...nada. This is what came of it today so it will probably get gessoed over tomorrow. Sometimes after you re-work so much it just feels tired and wrecked. I feel like there is a new painting waiting somewhere in that canvas, ready to come out.
Beneath the pictures are photos of the wood canvas box support I mentioned the other day. Kelley asked me what the heck I was talking about - I think I could have come up with a better description - so here they are : )
