Interest Check! Bio Bubbles!

Hello everyone! Smol interest check for some bio bubbles aha. I had lined and colored one of my OC: Torque (he has fancy lettering in his name but I don't feel like fancy lettering right now) and I was wondering if these would sell for, and how much they would sell for.

A general idea of how they would look like: 

Your wolf would be in that position, holding it's tail while a bubble was around it. I'll line the bubble in a bit, but so far, thoughts? Would you buy these if I sold em as YWH/YCH and how much do you think is a good price range? I appreciate the help!

They're pretty cute, but I don't quite think the quality is high enough for me.

Quality? Could you possible go into further detail as to what I could fix?

It's not as clean as I would like, e.g the lines, and it's not very pleasing to my eye shape-wise

Thank you! I'll take your advice to heart and fix what I can
