The second picture makes the colours look much funkier and, while making the mini look cool and all that, it\'s not what the mini actually look like (I say this without having seen the mini, but I\'m fairly sure...). The first picture looks much more natural in it\'s colours and from experience with miniature photography I\'d say it\'s a pretty accurate representation of the real thing (at least a lot more so than pic 2).
So, my vote goes to pic 1. Nifty paintjob, BTW. I really like the skin and the metallics. I\'d work a bit more with the contrast on the leather parts, particularly on his right arm.
