Gosh don't feel bad about that. I'm working on a top right now where I made so many mistakes I was tempted to toss it out. The big prob. was that the cornerstones were tiny pinwheels that had to go just the right direction. I have so much $ & work into it I'm stuck finishing it. It's sandwich time now.
Yours is beaut. I'll bet your errors don't show up like mine do. Love your colors. Also love the "blowing in the wind" pix.
