Didn't take no time at all for this happen on Weasyl.
I hate to sound nasty, but READ THE DAMN RULES!
I am constantly being asked to do things that I put in the "WHAT I WON'T DO" category. I always, I as far as I can tell, put a set of rules when I open whatever it is that I am opening. Still, people ask, "will you draw me........".
The biggest issue is when I say, "be specific" and people throw a ref at me and say, "draw this". You just saw the word free and didn't read a single word otherwise.
Anyways, just read the rules I set and be courteous about asking. And at the minimum, say thank you or something.
I wonder how long it will take till others copy this picture for themselves, like my live-stream picture. Seriously, you could have made it a little different.
