Learning to sew: How perfect should a seam be?

Dress_seam

As perfect as I can make it? Or just good enough to crate it up and call it art?

As you can see, the right side is too narrow in the middle of this picture. Should I rip it out, dear readers, or is it good enough? I ripped out the seam on the other bodice-arm piece, and made it close to perfect. It was quite crooked, more so than this one.

I have a tendency to rip and attempt perfection. This slows down my progress immensely. It makes me feel hopeless. So. I wonder if it is better to get some completed garments into my closet, and thus boost my confidence that I can at least finish some dresses. What do y'all think?
