Ok, it's one of my non-chibi attempts, where I use to FAIL u-u I wanted to do an acceptable serious drawing of mio, from K-ON!
I'd like to know if you see any major mistake, and if you could redline it, I would love you forever ;__;
thanks ~

FFFFF I love Mio :D She's my favorite! I'd redline for you if I could draw ;P
i can;t redline, but the only thing i'm noticing is that the foot on the ground is a bit smaller than the other. looks amazing though!!
There are two things I noticed that looks a bit wonky. Mio's eyes aren't the same size. She's facing towards us completely (her face anyway), so I'd assume both eyes should be the same size. And I'd also move the eyes slightly closer (maybe 1 eye's width's worth) to give it a less 'retardation' look.
And also, this might be your style and whatnot, but since you're trying to draw non-chibi, I figured I'd also point this out because non-chibi should follow a more non-chibi proportion. Compared to the arm length, I find that the legs are slightly too long. And also, without even following the center line of the body, the way Mio's left (from our view) leg bend is really awkward to me. I think it's because the way the legs are positions.
Mio's body is kind of facing towards us; but the way you drew her right (left leg in our view) made it seem like her body was facing to the left.
I will try to do a redline when I get home; but I might not be able to since I'm packing for a trip to Montreal. But I hope what I said made some sense c:
