Great colors, overall it's oversharpened in some areas. Instance, the yellow C4D on the right and left side has too much pixelation, as well as the helm, neck area, and his shoulder. Fix the sharpness issue and it'll be a great sig.
The plasma bursts seem like they are coming from behind the odst and yet the light source is in front of him. It just doesn't add up. I like the movement they have, but I'm just not feeling it. Maybe if they were sharpened instead of blurred to make them look like the other shapes.
looks oversharpened to me... it just makes the depth not work as well.. maybe a more gradual/less extreme sharpening. good work on implimenting the c4d though.. even though a rainbow c4d doesnt work amazingly with a darker theme such as ODST
