Face Constructive Criticism Please

Hello! I'm new to the site and I'm looking forward to creating my first game. I did use the RPG maker on Play Station on playstation so I'm at least not a total n00b. Anyway, I'm trying to create some face icons for my game's characters and I'd really apreciate any constructive critism you can give me.



I've been trying to develop my own style recently and I'd really appreciate any constructive criticism you can give me. This pic is some of the same characters found here (http://www.sheezyart.com/view/903179/) with a few adjustments to character looks. I know this is a bit rough. I figured I'd fix it up after I got some pointers.

Thanks 

Those look good. Im sure they are just mere sketches but its a good start.

Try not to have them all face the same way and change the postion of the head. As in angle.

I've realized the cheekbones were friggin huge after flipping them in photoshop. A little compressing action and it's being fixed.

It's always good to admit to yourself when you think there is something wrong with what you did. It's a quality.
