Not really, at this point everything is a learning experience. In bowmaking there are NO MISTAKES...just some design executions that are less efficient.
For instance, if a bow breaks just outside the fadeouts on the bottom limb, that means it was designed to be shot by a VERY short person...though with only one limb it is really inefficient! *grin*
Keep at it, and post all your questions, no matter how minor they are. We are all happy to help you out.
