There's three titles. You know there's a description. When you submit an animation, there's a "Short Description" and "Author Comments". "Author Comments" is your description, where you can put text (which includes bold and italics), images, and of course links, where you could link your Patreon and also the source for the music you used.
As for the loop, it's a bit choppy, but otherwise it's alright. It uses frame by frame, but the same loop is sped up to do running. Doing a 1 second loop is a whole lot quicker than doing even a 30 second animated short with writing, voice acting, etc, of the same quality. And to save even more time, there's very minimal shading and a patterned background.
Also a bit of irony, hypocrisy, or whatever people want to interpret this as. This animation uses the Cheemy / Bonk / Go to Horny Jail meme, yet you also post NSFW stuff.
