Random sketches

Please forgive me if this is posted in the wrong category, this is my first time here and the whole category thing is so confusing... Ehm, anyway. Just some random scetches I did of my original character, Ishajami Yumar. I'm bad at showing age differences, but he's supposed to be 13. Shocking, yes? Maybe it's just me, but he looks like a 10-year-old in my eyes. Oh, well...^^
This is just an attempt to draw different facial expressions, so ignore the mistakes in it, okay? Then, I'll be very happy. Originally I had just intended to scetch with pencil and leave it as that, but the inking pen lay in front of me and begged me to use it. Inked or not, it's still just pretty random sketches. Ah, but I luv him anyway. ^_^
