Well, yes, some of it. The one I just favorited is one I would really consider. Depends on my mood and money and how it looks in reality. With that said I think maybe it's a good idea to fill your gallery more so you'd have more products and experience. There's still room for improvement though and that shows. XD
As for most cons, fan-art is apparently what sells the most - though not the only thing. I don't really know though because we in little Norway don't have much cons.
