Never gonna give up

I'm working on making some patterns for my book Sexy Knits. I envisioned a cute tight cropped tank top, and I set out to make it. I've been excited about making this for a long time because I decided to keep it for myself (sorry I'm not sorry) and it's the perfect top for going out! After all - what's better than getting a compliment and responding, "Thank you, I made it!". LOL just kidding… maybe. However, the shirt didn't turn out how I wanted it to. I still love the concept, but there are just a couple of adjustments I have to make. The shaping in the arms need to be cleaned up, the shirt isn't tight enough, and the front of the shirt curls a bit - which I'm still figuring out how to fix! Any advice?
