I make my characters mainly for roleplays - either freeform roleplay series with friends or (these days) D&D. I don't collect designs nor trade in adoptables - any designs I do end up accumulating from other people have been received as trades on character games. I mostly have no idea what to do with them myself so they just sort of sit there. :P
That said I do like making my characters visually appealing (which doesn't mean "pretty" but does mean "interesting") so that I'd enjoy drawing them more. Most of my art is roleplay illustrations as well.
