I suggest opening paid commissions and posting these pre-paid pictures on Newgrounds, while keeping your un-commissioned work behind Hentai United if you wish. That way, you would still get paid for your work, the buyer would get a custom picture, and the general population would get to see it.

On the picture itself, what I can see of it is good. As always, I like your style, even among other anime styles. Your facial expressions are intense and your shading is basic and charming. However, when everything else is shaded, why isn't her flower? The petals, plus the light source, would cast shadows on it, and none are there.
