What exactly do you have in mind? Professionally I'm not sure about my character skills yet but I can certainly do backgrounds and stuff for you, also, I only joined this forum a few days ago, I'm working on a manga myself.
Tell me what you want and I'll see if I can't get a rough sketch up, i.e what kind of scenes in this highschool theme
Pretty much anything. If it's a highschool theme (classrooms, people going to school or going home, teachers, students, bicycles, and so forth) it's good. Seasonal themes play strongly, especially fall/autumn since it's the start of school, and spring/summer.
Themes/styles I am looking for:
project a-ko
sailor moon
gunbuster
macross (and macross frontier)
bubblegum crisis
ranma 1/2 (scenes like when going to and coming back from school)
totoro (school scenes)
naruto
hikaru no go
i'd lke to avoid sharp lines and distorted character developments found in places like:
dragonball
vampire hunter d
fist of the north star
one piece
Just off the top of my head, a general idea. I guess you could say I am looking for KyoAni style (see:
