20 points is more then reasonable :l I've seen people asking for 30+ for pieces that look like scrap, like a 5 year old drew it or otherwise they half hazardly painted someone else's line art. My price stays because of time spent in the MSPaint program and having to do research on each shiny. My pride is, I don't use someone else's line art.
It may take a while, but they'll be adopted! I have hope!
Mhmmmm well that's fine. I'm not saying that your art is bad, just that they may be slightly overprice, but I'm sure there's someone in deviantart who will want to buy them. Plus I really hate people who color lineart sloppily and then sell them for like 30 points. >.< Well good luck! Was just a friendly tip if it takes too long for them to be adopted or something.
