Hmmmm... Bases are kinda cheating when it comes to stuff like character design. Meme templates or biography charts can go under Miscellaneous, but bases for designing characters I'd have to say no.
I want to promote people practicing and perfecting their drawing techniques, and tracing over/adding a few details to something already done for you doesn't quite accomplish that, at least in my opinion.
I hope you can understand my perspective, and I want to thank you for joining and asking about this first. If you have any other works, feel free to submit those!
