Yasiel Puig sketch card

I'm about to do a new painted sketch card as part of a trade with another blogger. I haven't done much artwork recently, so I wanted to sharpen up a bit and practice. I decided to draw baseball's current most interesting player, Yasiel Puig. I found a photo I liked, and start drawing.

Overall, it came out ok. There are several things I could have done differently, but not bad for 30 minutes worth of work. His signature is pretty basic, and was an easy add to take up some dead space.

Now, what to do with it? Just set is aside in my collection? I checked eBay, and far nicer sketch cards of Puig go between $10-$20. Much, much nicer ones. Maybe I could get $5 or so for this one. Is it worth listing and see what happens?
