yeah.. the anime girls get that scratchy blush stuff when they're doing something naughty! O_o

I think you did well at having her head shape/size being in proportion to her body, since most anime or anime-influenced artists tend to draw heads way too big.

She's blushing because she's shy and there are so many people here. And because I thought her face just needed something extra. And anime don't ALWAYS blush when it's something naughty. They could just be embarrassed. Thank you redpanda, I try to be proportionate. :D
