This is really good! Working on making them smaller would help it look better as an icon on here (which sucks bc the large version is super cute as is). I would definitely consider ordering one of my mayor. I think anywhere between 100-200 TBT would be fair!
I usually work on large canvases then size it down if needed. As long as the proportions are right then the drawing won't be affected.
I would also love to order one of those icons when they're available ehehe. Maybe around 150 tbt for an icon?
I can totes relate to the struggle of being used to draw on a bigger canvases then having to down grade to ones like 50X50.
What I would normally do is draw a ruff sketch then down size it to what canvases size it want.
Anyways you can deffo get around 100-200 TBT for theses!
I agree with the prices suggested, somewhere between 100-200 tbt ^^ I would definitely order!
I relate to your struggle with icon sizes though ._. one thing you could do is do them on a large canvas and offer both the large size and an icon size (like the one you resized for yourself)
