Actually for all the Reds and Blues I used GW shades. For the reds I started wtih Scab Red, and for the blues I made a mix of Enchanted Blue and Midnight Blue(more Midnight B. of course). To shade like this just keep the consistency thin and you'll be set.

Looks better now, I really like the combination of the collar and helmet, and the pose is good. Could you tell me what colors you used for the blue and red (if GW ones were used) as I´d like to paint some CF myself
