Andrew, looking good man, they are pretty nice poses to for Tamiya figures.
Did you fully assemble before painting? If so, how did you find doing the detail in the hard to access places, under arms etc?
I think the colours look fine, are they acrylics or enamels?
The finish looks a little shiny, maybe it's the flash, or maybe you will be doing a matt laquer finish?
Well done though, let's see more when finished. :-)
