I think this thread is perfectly fine here, as they're providing and sharing character design ideas. Not making a tutorial on how to make a character or put a good character together. Therefore, it'd be best for the thread to stay put here, as the 'Characters' board is generally for any topics/discussions/ideas regarding characters. On the other paw, the 'Character & Roleplay Tutorials' board is for tutorials created based on characters and roleplaying.
Unless the thread is modified and completed to show otherwise, once they're done with the W.I.P. stuff, then a decision is best to be made once a thread is complete.
I look forward to viewing your character ideas and designs for everyone, Jazzie!
I am excited to see what you have in store for us Jazzie!
