Hey, Uruk, those look fantastic! The unmasked berserker looks like a Beast!!! They both look very cool! Your repaints looks great, as usual!
As for the armor, it may be a bit bright. I took my photos at work, under some harsh fluorescent lighting, and then brightened up the pics... hmmm, now you've got me thinking. I used production stills from the movie, and the paint master promo shots as reference. May have to tweak him. Here he is in a different kind of shitty lighting...
Like I said, he was a pain.
And to samoht, all I use are cheap acrylics, mainly the brand "Folk Art", and a few nice Tamiya paints, and a few by the brand "Americana", and "DecoArt"... And I usually use Matte clear coat when I'm done.
