Looks good as a WIP, but painting the shoulders will make the shoulder pads less than solid once stuck, as the glue will stick to the paint not the shoulders! (Learnt that the hard way before now!)
Giving you an 8 for the gradation alone. Id like to see a finished marine from you though. The gem style eyes are very nice, you have some great potential dude. Very seemeless shading. Another idea might be to add chips to the armour and highlighting the chips to creat the illusion of depth if your into the worn look at all.
Comment on my pics if u get the chance
