I recently did my first paid gig working at a convention and I'm going to be using a chunk of my pay to commission artwork of a couple of my characters. I've never done this before, but I know artists like having plenty of references so I need help tracking down a couple of things.

Things I have refs for or can prepare on my own:
-Clothing
-Weapons
-Colors
-symbols

Things I need refs for:
-body type (proportions and physique_
-face shape and traits (eye shape, nose, mouth, etc)
-hands/feet
-hair styles

If anyone here regularly hires or makes commissions and knows where to find reference images for these things -or can think of anything I might be missing for making a proper commission request- I would greatly appreciate some advice.

Additionally, I could use suggestions for artists who are known to do good anime-esque work as the character(s) I will be purchasing artwork for are original characters for the web series RWBY. Full body work (this kind) is the minimum I would like but a full concept sheet (such as this) would be ideal (in case I decide to have more art made at a later time)

Any advice on hiring an artist is greatly appreciated, even if it is not of the sort specifically requested here.

Thanks, and have a lovely day.
