Another Radial Design and Etsy(?)

Here's the latest work I've finished. It isn't anything special in my mind. Not a painting but in colored pencil this time. I started this one day while subbing in a high school math class where I had absolutely nothing. to. do. I've worked on it a bit here and there for the last few weeks but had a huge chunk of time to finish it while I was subbing for a Spanish class and watching Shark Tale (in Spanish) over and over. Boring! 

It's about 7 3/4" square; a decent size. Although I don't think it's too special overall, I am rather proud of the blue background. For a while the drawing was taped to an old textured cookie sheet I have and a blue pencil helped create the background. 

I've been painting these small works for a while and when I'm done the artworks get put in a closet. I don't have the time (or wall space) to put up a bunch of my paintings. And really, I wouldn't want to have to look at my own artwork all day. I have a couple paintings up now and I am my own worst critic. I don't like looking at them at all. 

One of my readers asked me what I do with them and if I sell them. I was rather flattered that she asked! I do have an Etsy shop but I haven't sold anything there for a long time. I'm thinking to give it a go with some of these small radial paintings; getting them matted and posted on Etsy and see what happens. 

You guys have seen them. You've been around. Any suggestions on price? They are all smaller than 9" square. 

I'm not looking to make a fortune off Etsy or anything. I paint these because I enjoy it; it's a problem solver for me...but I can't keep everything I ever create! I have to do something with it and I might as well sell it to someone who's actually interested in them. 

Any constructive criticism or advice would be greatly appreciated!
