Well don't we have a rather creative person on our hands? XD That's a good thing though, no worries! You'll find that you'll most likely be spending the most time here on PC in the aforementioned Pixel Art forum that Cirno linked you to, and if you're into ROM hacking, you can check out our Emulation forum since you have such a huge passion for ROM hacking!
All in all, I hope you have fun here wherever you decide to post! :3 This place is awesome just because there's so many places to post, so one can hardly get bored being here~
