It seems I need to make it clear even if I mentioned it in my comm info. So I draw a commission ONLY AFTER THE PAYMENT!!!
Not so long ago I tried to make an exception (I belived in some shitty excuses), made a first sketch but the dude wanted it be more detailed. And when I asked for payment for futher progress thety're just blocked me on discord. Nice, I spent my time for literally nothing.
So yeah now Im trying to avoid sketch free-loaders more harder. If you want get a wip sketch beofore the paymen so bad - just look for another artist.
That's all, folks.
