I'm not sure if I want to go brighter or not, but I suspect that the lack of contrast (a first for me for this type of image) is not working very well. The lack of whites is definitely working against the contrast.I'd go for brighter and maybe clarify more.
One thing I knew about this photo (or thought I knew) is that the composition was not the problem. So when I saw your comment on my phone I thought you were nuts. I thought about it some more and concluded that you may have a point.And even tho the building may be leaning that much I'd pull it up on the right. The heavy leaning tree and shack together is bothersome.
