Do not take any work from Xdragonx10. They go around looking for young and inexperienced artists right here in newgrounds and gloat about how little they pay them and work them into the ground with tight deadlines. He takes advantage of those that are inexperienced and then advocate that this is a good thing.

This is not about being greedy, this is about being properly compensated for your time and effort. I'm sure he wouldn't appreciate it if someone gave him the run around like this for his scripting work. So if you get any offers from Xdragonx10, just turn them down. He will only abuse your skill.
