Oh, yeah, self-pity. Real mature. So what if YOU like what you drew for someone else. It's not all about you, and what YOU like. You open requests and when you draw something for someone, but then decide you wanna make it something creepy and irritating like that shitty Sonic.EXE shit, OF COURSE people are gonna have problems. You get a request, and people expect it to be just what they ask of you, not to take it and turn it into something YOU want. It's not a matter of ungratefulness, it's a matter of YOU not taking the interests of the person making the request into account. You like Sonic.EXE? Fine. Don't force it onto stuff you're doing for other people, unless they EXPLICITLY ask for it. You're not a terrible artist, you're just not considerate of others. You're fucking inconsiderate of other people's feelings. Stop blaming OTHER PEOPLE for YOUR FUCK-UPS. Stand up, put your big-girl pants on, and realize that the world doesn't have to stop for you.
