first of all they show a big improvement in your skills. I really like them - they all look cool together.
second of all - I heate the sculpts. They are ... poor, man, really can't compare with the current minis.
and for some comments: your blending is getting better and better but it seems the last highlights on the black seem to be rushed. there is a pretty nice transition and then - oomph - the last highlight hits the minis. you could use more intermediate colors, or simply thin the last color more and add more layers of it (covering smaller and smaller areas still with ther same color, but waiting for the previous layers to be dry to avoid brushing them off).
as for the metallics - i thin k they could use some more highlighting to accentuate the edges. They look too "soft" for artificial objects, and the details get a bit lost becauise of the lack of the last highlight. The washes could be a bit neater, too. Do you add a drop of dishwashing soap to your water? This could help you apply the washes smoother.
And it seems you could use a new brush. You would be able to improve even more and save time, which matters....
good job! continue, please
