Ohoh, i guess that's what you call 'lost in thought'... she starts to levitate :) !
Anyway, i love the sun and the light effects (sunrays and sunspots), it has an 'old manga / anime' feel to it. The girl though is your usual perfect drawing : great colors, shading is awesome, and clothes / accessories design is top-notch... but the winning thing is the look on her face, she really is in her own world (so forward a few thumbs up to Omocha-san ;) ).
Thumbs up for you too, and fav !
