I reckon you should revisit this picture mate, and finish it off. The helmet is off to a great start, and I am loving the asymmetrical breastplate. I like where you're going with the areas of details you've already fleshed out on the armour. You've got glowy effects down to a fine art, so you'd be able to sex up that weapon he's got strapped onto his forearm.

If you don't reckon you have time to fit in new pieces, then surely you can squish in salvaging some of these older pieces mate. It'd also be interesting to see how much you've progressed on one piece of work, keeping the older elements, and adding to it with your l33t new skillz.
