This one is the most "finished" , because it took me the longest. I'd say it took a week to do with maybe an hour or two daily and maybe a few days skipped =P The likeness is based on Sandara or Dara Park from 2ne1.
This one was really fast but getting the concept for it and a rough sketch I was happy with took a bit more effort than usual. The likeness I used is Yuka's face (japanese street fashion model).
Also , I'm trying to get better at backgrounds. It really isn't my strength especially since I usually just leave it white but I realize sometimes a proper background is needed.
I would not normally draw something like this, but it was for a contest on Deviantart that requires you to pick a drawing you submitted in the past and redraw it. In this case the drawing I picked was from 2008, hence the anime-ish look. Not my favorite, but anything you draw is good because it's practice!
As much as I love portraits, I want to/should work on full body stuff for next week :p
