Awesome work. Don't for a second think these don't look as good as mine.
Truthfully I've been thinking of diverting my attention to my Deathwatch because their rules are being updated (rather lethargically) but then I see your thread here and.... wow. It's some awesome work here. I love the basework too.
I think you know this is good stuff. That attention to detail, the scratches, highlighting. It's all great stuff.
Like Panzer said it's just a clean variant, whereas I really wanted to go with a group of White Scars that are really.. quite busy doing things in the dirt. Lol
For myself I had been doing super clean ultramarines, super clean armies like Thousand Sons... even my Deathguard were pretty darn clean.
I started experimenting with oils, and more oxidized metals, weathering with powders, isopropyl etc, etc and when I decided to start my White Scars I needed to reinvent my skill set a bit and liked the look and challenge of it all on White Scars.
That said I fully appreciate the beauty of what you've gone and done here. Don't sell yourself short. I love the stuff you've done here, and as mentioned it's further motivation for all of us.
