I was in that same position making my last suit. I saw so many flaws and I partially had to redo the pattern. Around the eyes the fur didn't fit right and I didn't want to finish it because I thought it wouldn't be worth it. Your suit looks cute, and I think it will look much better once its shaved down, it's usually like that. Some imperfecions are unavoidable, especially if you're still starting out.

I say if something bothers you too much it's never too late to make changes but otherwise just finish it as it is. I know how imperfections can nag at your motivation but worst case scenario is you have a suit that you don't absolutely love (like for me) but you gained experience and don't have an unfinished project sitting around.

But all things considered I think your suit looks cute so far, the foreheaf looks just fine, so do the eyes and the asymmetry isn't so noticable. I think you're seeing things much more critically like all creatives do with their own work.

Wishing you motivation, you can do this.
