Kiari - Black and white combinations for the win. It looks really well balanced out with the right amount of blacks and whites here and there.

Monmon - Its such a beautiful avatar really but perhaps the one thing which looks weird in it might be the skull on the hat. Having that white spot there is kind of distracting and it makes my eyes search for another white spot elsewhere to balance it out but there is noe :(

Chronic - eye sore? I believe you may be in the midst of working out something new and fresh and it shows because your avatar is naked apart from the water themed items. I think you are definitely going to come up with something really cool looking!
