I like what you've tried to do, but I think the camouflage pattern is almost lost in the mass of detail on the model. Oddly, when putting camouflage on a mini, you have to do the opposite of real camouflage a lot of the time: making it stand out. Less blacklining between armour plates and painting more of the rivets in the same colour as the armour would have helped make it clear that the armour's camouflaged rather than just dirty.
