Eldar Farseer by astarsis86 @DA. - Why is the ground glowing beneath his boots? Wait. ENHANCE *zooms in* Why is there dotted lines around his feet- ya know what nevermind. Keep being you Space Elf. I'll go be my lowly human self over here.
Striking Scorpion by Althwen @DA. - Looks like he shaved a little off the top for that Ultramarine. - Also Batman gauntlets. Awesome.

These next 2 are done by the same artist at different points in time. Old works remastered and artwork progressions are always cool to see.
