I'm not a shouter, you see what I upload, you see who drew it. You can make your own decisions, but one piece of information you're probably lacking is how much it cost.
I'm usually wary of paying artists by the hour, it seems like you're screwed if they're on a bad day or have an art block, but today I sent supremekitten $18 and said 'Draw me a cute Umbreon cub girl in every position you can in the time allowed'.
By the end of two and a half hours (two normally, but you get discount for buying multiple times like I have), I had no less than twelve sketches. I'm not kidding. Twelve. $1.50 per sketch for some of the best I've ever bought. I tend to believe that sketches have a purpose. I prefer full color art, but a sketchstorm like this will provide ideas for my next few full color pics.
It's quite likely that many of those will also come from supremekitten at his insane price of $30 for a full colored picture. Seriously, if you need ideas, or just have a few that you want sketched, go to this guy and give him $9 or $18. You will not be disappointed.
