hi hi, nobana-chan! :D ah i see this is a fanart, then.. :) well, i looked first at Arina's style, and it seems she draws bigger eyes than usual.. :) i saw the full view and i think, it's a very good and detailed drawing! :D the face is nice, although i would apply a more soft curve around her face and thinner lines for her mouth. :) and then i would make more line variations.. (eg. thick and thin lines on different areas) and i would add more volume to her 'frame'.. :) softer angle about her elbows.. :D beautiful details on her hair! XD like you, i don't like to draw bg either... x_x well, i hope you the best for the contest, nobana-chan! :D tc!
