Moments. by far grasped this theme the most and made the most professional and best looking icon. The colouration used is so on point to a style of iconage which looks extremely well. I can see technique used to bring out the colour of the lips. Nice use of gradient maps and nice stock placement. Overall the best icon here.
Followed by this was Signomi's entry. I admire her style, but more so for anime stock, it doesn't seem to work with real life images as much. The stock was nicely rendered also, which was a big plus in the amount of work done here. But the way it was coloured just bothered me a little. It wasn't quite on point, a little too bright in my opinion, high quality entry, but just a little over saturation.
Finally, Forever's. The stock's quality was reduced to begin with, the positioning was pretty bad, it should have been less of a close up on her face. Very little technique used and in general, was completely sub-par to the other two entries which deserve the votes here. Given the stock, this icon could have been so much better.
I'd like to see either Signomi or moments. win here, as both show some great quality and professionalism and lack beginner mistakes. I went with moment.'s purely because it was the icon I would use and seems to be the most eye pleasing of the two I found to be the best.
