overall its a very nice looking model, your after criticism though so ill do what i can
-stripes- the stripes look very good but there are some parts that i feel can be improved. the stripes on the back of his pants are noticeable thicker than those on the front and the stripes on his vest are a little bit crooked.
-loin cloth- majority of the loin cloth looks very good but i feel the deepest shadows near the top of the cloth could benefit with more shading.
-skin- his face is perfect, there isn\'t really anything i can see to do to improve it, the back of his bicep however and his shoulder blade aren\'t to the same standard, they look good and very similar but it almost looks as though a wash was applied for the final stage and came out a little blotchy on the back.
-metal- I\'m not overly fond of the metal, majority i feel could benefit from weathering and the gun barrel that is weathered i feel has to much, i would try to hit a medium, do all the metal with half as much weathering as is on the gun barrel. on the upside i think the application of the weathering is perfect, its just overdone.
-squares- like the squares, think they look fairly uniform and the off-white is nice, the one thing i will say is that i think the edges could be cleaned up a touch, very, very minor.
-boots- last thing ill add is that the boots look as though they had an ink wash, it looks good but i think an application of some sort of dull-coat or matte varnish to take the shine out of the cracks would enhance them.
i know this seems like a huge list but there all small things that will improve the overall effect of your model i feel, hope some of this was helpful
