I haven't really drawn much male character, thanks to Lemma. j/k. :3 I probably won't be able to do the art for you, but some sketches seen like a fun idea.
For an artist, physical descriptions are usually more helpful. Features such as height, build, body shapes, facial features ,deformities, preferred outfits, how they prefer to wear their hair, etc. You want to give them as much details as possible, and as much details that would differentiate between character. Focus on outward appearance in your description to the artist. Also without specification, you risk relinquish some degrees of creative control to others. Although sometimes I think that's what it might takes to keep an artist that you are otherwise not paying. More demanding artist might want to have more input with the game itself, if you were to depend them to flesh out the physical attribute for you.
When you have to write a lot of characters in a roll, there are certain homogenize sense in terms of some of those personality, likes and dislikes and feature. This could potentially make some of them much less interesting then other, and more so when in group. Personally, I think the scope of this game might have been a bit broad. I recommend narrowing or consolidating on character with stronger and more interesting attributes and personalities that would create conflicts (read: drama).
Kim wen sounds a lot like my sister's name. lol
