awww, sadly you and many people don't have much idea about prices, sadly
250 points it's just a little more than 3 USD!! do you think an amazing art is worth only 3 USD? maybe 30 USD, or even more!
100 points is a little over 1 USD... do you think it's okay to sell your art for 1-3 USD? I don't think so. I put a lot of effort, heart, and time into my art. that's why a colored fullbody, cell shaded is 1200 points which is ONLY 12 USD.
sadly because of the point system, a lot of people lost idea how much art is actually worth, and think like you, that 100 points is much. it isn't much, for the work people put into their art. would you like to do few hours of work and get paid only 3 USD? I doubt so.
