Excellent job on the blue armor! The subtle shading turned out especially well on his right leg.
Imo there is only one very prominent aspect on the paintjob that drags it down and that is the white pauldrons. They don't seem to be shaded much and the right one should have been filed smooth. That lump of metal/paint distracts from your otherwise impressive work. Touch that up, if you have the spirit to do so and it will give off an even better overall impression.
7+1 as an incentive to touch up the pauldron. ;P
