Don’t feel obliged to actually buy anything. I was told this more convenient than releasing the designs for free. And I liked doing them, a reward in its own.
If you have ideas for an original designs (= not fanart, even if that Bear can kinda be counted as one), let me know and I’ll see what I can do.
I release new designs eventually, I’ll keep you updated when the time comes.
