I just finished this thing yesterday. It's a small, very basic guide on how to pose in cosplay. I'm not a great poser, but I've learned a lot since I started cosplaying and this is mainly a small guide on how to avoid the most basic errors. Goodness knows I would have needed this guide myself back when I started cosplaying. I was so bad! XD
Anyway, the guide itself focuses a bit more on giving tips to girls, but there's a lot for guys too. ^^
I do hope this will help SOMEONE at least.
Guide: Posing in Cosplay
Edit: I just realized that this might not be the right category for this, in which case I apologize.
