After panel lining (using a Sharpie and Zippo lighter fluid), painting it and randomly applying decals (from other Gundam kits) to create the appearance of markings, I think I've finished.

It's my first panel lined and painted kit, so I know it's fairly rough and there's plenty of areas for improvement, but I'm fairly happy with the finished product.

It was made up for a group build contest with the theme being 'Ground War Grunts' - hence the dirty and militaristic look of it.
