I know that feeling :D Worst of all, I usually don't tend to notice when the difference is only slightly there. I got eliminated in bwlims (not active anymore on LJ) once because the proportions are supposed to be off. I don't see it but quite a few people commented on it...
The new one looks great!
But now onto my favourites (and maybe a little critic):
• movies20in20: costume looks really great! excited has a lovely colouring! joy makes it hard to see who is on the broom since the colours are a bit flat... (love the effect though) one word is simply brilliant - colouring, crop and everything :D orange - I want to say it's brilliant, but the "frame" seems a bit sharp and Albus could use a bit more contrast... but it inspires me to say brilliant :D pain has a great crop/scene choice, but the colours could have been a bit more vibrant and Draco a bit sharper (I really love using the Unsharp Mask filter for that so I have a bit more control over sharpness) weird is totally awesome. Just perfect :D
In AC#2 Harry's face seems a bit sickly yellow - but the all together all of your AC icons are great!
• hp20in20: enemy has a great crop, but seems a bit dark where Bella is concerned. That has it's own effect though :) text looks great! I really love the colouring of Luna! I also love the crop for Category #4 and all of your AC icons :D
• fandom20in20: I really love B/W, Dark, Fave Moment, Halloween, Plus One, Category #1 and AC#1 -#4. In crossover Severus' face seems a bit strange with how pink it is. And favourite Moment is perfection in itself!
I hope I didn't forget any icons I wanted to mention :D
