How am I doing? WH40k terminators wip

Slowly been working on these guys for a while. Hit a wall trying to figure out how to blend the purple in but finally forced myself to get back to it last night. Looking for feed back. Realizing I overly criticize myself so I'll let yall tell me what's good or bad.

I am definitely one of ones that will watch a dozen videos on how to blend and make smooth gradients, then not even attempt to do it the right way. Rather this is a bunch of pretty watered down layers.
