A lot of much needed paint apps here. I'm surprised you didn't give Scourge some red fingernails! Sentinel is the biggest offender of this group, your additions look great.
The white highlights on Skullcruncher are really nice. But I don't like the silverish-black on Hardhead's arms and legs. The other are great though.
Looks good. Didn't think before that would really make any difference; I stand corrected. I'll have to emulate, thank you.
