The depth doesn't bother me, it's the window up the limb, it's where you cut up the limb and violated the longitude grain, if it bends there at the fad it will likely pop at some point, I always make sure it doesn't bend down into the fads where the window is cut in. A lighter weight bow it will probably be fine , just bothers me a bit when they are cut up that far. Not criticizing your work just tell you what can happen, ask me how I know.
