Another character that I did got approved by the asset store today, it's a High-end rigged and skinned sci-fi robot, has normal map, a 4k texture atlas and is ~19k polys, but has a LOD version included with around 2.5k (which looks quite the same if not too close). PSD File for easier color, markings customization etc, is included too.
