FA, yes. I refuse to use DA nowadays since the freaking uploader there seemed to keep crashing on me every time I try to use it. Also, I hate using Photobucket because it's all ads and conflicts with my ad blocker... >.> Well, FA is the simplest one to use anyways. The uploader doesn't require a lot of BS-y stuff for you to do like DA does, and it goes through really fast so long as the site itself isn't busy.
I don't know about doing drawing requests just yet, though. I'm still working on writing ones... Oh, speaking of which, I just finished a semi-requested follow-up to the fic another person wrote for me. I would post it here, given that it was originally my idea, but I don't know how well it'd go over. It starts as a regular PokePark fic, but slowly turns into an inflation story (well, the setting is a new Area in PokePark that opened up, which allows Pokémon to blow up like big balloons).
