Your art is good and its not that bad. You DO have skill but for me personally it doesn't attract me as much as other artists. I mean don't get me wrong or anything! I think if you work on your style and try to make it more recognizable I would definitely ask for a commission I wasn't dirt poor ;A; (If you're comfortable with your current style then stick to it!! you don't have to listen to me or anything)
I've been on Deviantart for several years now, but I still don't know how the points work, nor do I really see a need to purchase the art that I find. I appreciate it, I save it to my favorites, and I periodically go back through and find that some of them have been taken down. When this occurs, I typically attribute it to the fact that these are the property of the artist. And as a result, they have that right. In the end, I suppose it's a lack of understanding of the need to do so, that keeps me from buying pieces of art.
