It looks purdy. Very neat, well made and solid, which may be a problem. I shoot at a bag against my shed. When I pull an oops, and hit a landscape tie, I sometime lose the arrow. They are b*tch to pull out buried in solid wood.
Do you plan to put a cover over that target? It might be a good idea to get something heavier, and instead of lifting the cover right off, to pull the bag out, and set it back in, tucking the cover loosely, between the bag and wood frame.
