uhmm, I can do three styles; Manga, Realism, and Semi-realism.
For Manga, it can be balck n' white or coloured (or I can do it where it's mostly black n' white, but one/some parts are coloured), Realism is ONLY in black n' white(or uncoloured), and Semi-realism is ONLY in colour (or uncoloured(uncoloured would not be done on the comp)).
As for how I do it, I can draw on the computer (using photoshop elements) or draw traditionally for manga (though if I draw traditionally for the manga, I'd rather it be in black and white because I don't have many colours for my markers.... only about 10 xD), for realism I only do it traditionally, but if you really want I'll do it on the computer (it just won't look as nice), and for Semi-realism, it's coloured on the comp.
If you want a specific pose, pleasepleasepleasepleasepleasepleaseplease give me a ref... especially for realism.
Now, I can do bust, waist up, full body, or headshot for any of them. But for semi realism and realism, I'm best at busts and head shots.
That's all you need to know.
Since it's freebies, you don't need to give me specifics. If you don't know what you want, just say "I want this drawn."
If you want something specific (like if you want it in manga/realism/semi-realism, or coloured/black n' white), make sure to say that.
I have 3 other things to draw, but I can't finish those until my stylus comes in (my stylus broke a few days ago, so I had to order another one. Should be in by Tuesday at the latest). ^-^"
