Assassins Creed Brotherhood

Ah yes, the brotherhood. A powerful network of multiplayable characters.
So let's start. The overall tone of the piece still makes it feel dark and somewhat serious. I honestly would prefer if Ezio's eyes were not seen at all. By blocking it out, it gives a better "assassin" feel. I think the doctor and the priest were done very well. There is a good balance between being overly adorable yet not silly that usually comes with the idea of chibi art. Your detail of Ezio's armor is very accurate and well executed.
I very much feel that this is a pretty good chibi rendition. This is probably my preference but I would've placed the characters a little closer together. Or, maybe have a gradual fading of color to accentuate Ezio more.
My last suggestion is to give them a more signature feel, like the way the doctor has the long nosed mask and the executioner has the hood.
The blues are divine and you captured the Animus feel very well.

Overall, I say well done. Chibis done not for over the top comedy but as an alternative perspective is well executed. You have accentuated my live for the AC brand even more. I want to our and find plushies of these to snuggle with or display proudly. Insieme per la vittoria <img src="e.deviantart.net/emoticons/c/c…" width="20" height="20" alt="" title="Clap"/>
