Except by 'your drawing', you mean 'you tracing over my drawing and calling it yours'.
I don't mind of people make derivatives of my work, so long as it isn't a blatant rip off and credit is given where it's due. Asking for permission, or at the very least a "hey, I did this based off of one of your drawings" is all I ask. It's just common courtesy.
If you can provide a link to the original or to my page, or at the very least credit me for being the creator of the original piece you used to make this, I won't mind if you leave it uploaded here. A heads up about it would be good too. Otherwise I'm probably going to say something about it.
