Although I think that chrome would be better as a secondary color, I have to admit that you're pulling it off pretty well. You may want to rework the edges of the forearm, though, since the color seems to be pooling in those areas. Besides that, the forearm looks pretty cool (and shiny).
The chest looks amazing, and it looks like you're ready for resin. The only suggestion I have for you is to use a little Bondo to smooth any rough edges you find. On such a finished model, most unusual edges will be noticable.
Try to put some lights in the ab plating area, as well. With chrome, the light will reflect everywhere (and, whether or not that is a good idea, I have no clue). You'll look like Arnold Schwarzenegger if he ate a glowstick.
