I would say keep at this one (while being safe!). While I'm still getting bows under my belt, I can say from my own profession that one of the things that separates a novice from an expert is being able to continue on with the project after making a mistake or if something doesn't go according to plan. So, maybe you can still get a shooter out of this bow.
Also, as long as you're learning and having fun, that counts for something, too!
