These icons look great, but I think a few of them look a bit out of place.
I like how most of them have black silhouettes of the main characters: makes the icons have a lot more consistency. Which is why the ones where you colored the characters in (Sly Cooper's Level 2, Sackboys Level 1 and 3) look a little out of place.
Not trying to insult your artwork or anything; I really do think these are great! Just one guy's opinion, that's all.
Great job again!
However, I think you could keep some symbols as silhouettes too, like Zeus' level 1 [highlight the bracelet] and Sackboy's level 3 [highlight his zipper thing, like in the intro]
I just think they would looke much cooler with this
