To start, great job and the only problem here amy.
The background water drop effect came out amazing and the the grayscale gave the piece a solemn feel, like something was missing. very well shaded, the blur effect use- brilliant. the way you added color only to the area she cleaned off was a very impactful addition, excellent job there. love the detail and clarity of the area far from her.
Now for negatives.
Amy... what happened? the outline looks like a sloppy photoshop cut and paste. the chrome effect on her wrist-ring came out great, and her back is very defined, well done. the hair and arms are all too blurry and the sloppy edges really take away from the pieces beauty. the detail, besides the hand that should have been more open, is excellent and well drawn. great texture use and shading, just a lil messy on blending. blend the shading on the hair more and the back and it will be solved. the shape of the part she wiped off should be more accurate. when u wipe a window, it is not that random. overall this is an amazing piece and it gives me great pleasure to be able to critique it. Keep up the excellent work, always seek to become better~
Love your choice on coloring :3 And great detail on the rain drops
I like how you drew Amy too :3
I so love the waterdrops and the shading. Just gives a fantastic atmosphere
