I might have one. Not...too...sure that I have references.

I can work with descriptions just fine c:

Alright. Gonna be hard finding a character, since I'm quite attached to most of the members of my...ahem...pokeharem, so to speak.

Off the top of my head, I have at least three Characters:
A) A busty Archeops who I named Cheryl for some reason
B) An Emolga- thin, c or b-cup, wide hipped
C) A Mew in all her flat-chested adorable glory
or
D) Me...since I do moonlight as an Umbreon from time to time

Take your pick, Quillfriend. I would love to make this an art trade if possible. I could use the challenge.

And what kinds of attentions do they like from their potential partner @ my guy (and any prefs on hair/style?)

Trade could be fun! I'll do this sketch first so I have some ref for this guy online (oops)

A) Cheryl's probably the most lenient when it comes to what attention she's getting. Apart from the obvious, she'd probably love having her breasts/ass groped during intercourse. You're free to give her whatever hairstyle you'd like if you pick her. Chances are, if I draw her, I'll follow your design to a point.
B) Emolga's a virgin. I do not know why. Also pixie haircut because reasons. Don't be afraid of having her take it rough. Most electric mice are capable of taking anything thrown at them, and Emolga's no exception.
C) Mew'd probably likes being petted because she's smaller than most of the guys she's with. The slut.
D) I'm...um...not usually the one being boned, so your Mewbro's dominant personality'll shine in this scenario.

I'm going to bet you're going to go for either Cheryl or Mew.

I have a weakness for smaller breasted girls with short hair /hnngghhhhhhh!! Emolga calls to meeeeee (but we'll see what happens)

O AO I feel you there.
