The bottom don't look that bad,maybe a little hinge the first 1/3 of the limb,but the top needs some attention or it will probably be short lived,you need to work either side of that hinge and then if need be pike it to add a little weight back. Tough piece of wood to tiller.
I normanly don't like to bad talk someones work,if I can't find something good to say I keep quite but you ask.
