MDG Archer Lineart

Bloody hell, this should have been finished months ago but I'm finally done the lineart. Next step is to colour it obviously and only guesses as to how long that'll take. The original image is about 5000px x 5000px which is really starting to eat up my memory with every added layer of detail. Unfortunately most of the detail is lost at this size but it wouldn't be me if I didn't put it in anyway.

I'm lost as to what colours/camo I should do this one so I'm listing to any suggestions anyone might have.
