these textures looks good,try making them in 512.
the 1st set(blue):
-it looks cool,but the foots dont looks good mapped.
you can add more details,such shadows,lights,lines and a good mapping.
thr 2nd set(robot):
-again,the foots are messed up in the mapping.
but now its great in the texturing part.
the leg looks cool,i dont have much to say about it
and try to make sets that mixes with the force color
