i have to agree with both GW & Tadao.
first, GW's pick.
nicely drawn, and you have captured the shy and/or disgust emotion of how a nice gentle girl would look like. AND GLASSES!
and secondly, Tadao's pick.
naked or not is actually not an issue for me, but it's the overall looks & colors that took my breath away. especially her eyes... those eyes...
"lady, i'm all yours..."
generally, i can see you usually used pastel like tone for the sketch, and more vivid colors on the final touch-ups. and it all looks great. the one i like the most is actually the one you did for your friend's role play. the way you make the "lighting" effect is just beautiful.
try adding more tiny details on the dress and sword, but with the same silvery tone. it'll be good. yeah.
