I think its an awsome model and I can't wait to see it painted but the only thing that bugs me is the Purity Seals. 2 things:
A) too many, my eyes keep going to the seals and not the actual model, but thats up to you.

Fluff wise, Power weapons destroy any matter that they come into contact with, so BZZT, no more Purity Seals
Now you can keep the models as is and I don't mind but you did say you wanted to know what we think! ;D
