The blush is very well faded to her red skin tone and the muted background contracts nicely with the brightly lit foreground. The wrinkles in her clothes and shadowing is colored smoothly. The facial expression and hand placement is also well drawn for the cuteness factor. The way she is looking at the veiwer involves the veiwer more and makes the drawing more personal. Although I would usually complain about you not filling in her glasses' lens, I'm happy you did not because it would take away from the blush (and because her lens wasnt really shown in the anime).All in all this is very adorable and amazingly drawn.
