you have good cropping on#5,6,9 but you need to work more on the coloring like #2 it's too dark and unnatural(that green coloring on Demi's face is weird) try to use the coloring like in#5 #7 looks grainy be careful when sharpen the image and the text in the first icon doesn't seem to fit with the picture
for the coloring I suggest you join printless so many pretty coloring over there
hope these might help and I'm sorry if I make you confused or sound kinda rude because English is not my mother tongue
i agree with kopgirl, on icon #1 and #2, that's too dark and green. #5 is really good! colouring and crop. i like #3 a lot, also the use of text is lovely! as for #8, i don't like the cropping, and also the frame - i think it's disturbing on a close up of the face. and #9, great work! colouring is nice, sharpening is perfect, cropping as well.
