Jeremy,
I was a bit bothered by the fact that the off-center view makes it a little unclear that the gate is sagging. The steps above it are nicely horizontal, but the step just below the gate appears to slant. I played a little with the perspective (using one of my favorite obsolete plugins, Image Align Pro), trying to keep the upper stairs level and getting that one lower stair level, too. The result, as I see it, lets you see more clearly that the gate is sagging on its hinges.
Does this improve it?
