17 - The icon appears oversharpened and overbrightened.
05 - The circular insert is overbrightened and the 'stroke' border appears jagged as if it was applied before the layer was resized.
12 - The cropping on this icon does not make full use of the 100x100 format. Jorja's face occupies only one half of the icon and there is nothing in the left-hand half to draw the onlooker's interest.
11: The resizing made the image look a little weird
07: The colouring is overpowering and the icon is a little distorced.
05: The white circle seems out of place.
#11 - cropping is a bit off and the border clashes with the text colour
#7 - the images are blurry and the colours don't match
#17 - seems "washed" out and bit blurry
Thanks for pointing that out, Lauw I'll let it slide this time since voting's already up but next time please remember all that the max pixels for icons are 100x100
07: The image seems squished which distorts the icon and lowers the quality.
11: The border doesn't match the rest of the colouring of the icon, and it's a tad too thick. Also the image is stretched too far inward.
17: The image is too sharp.
