This weekend I finally finished off painting my Eldar army. While the Craftworld is obviously Alaitoc, I've built it up in a more balanced manner so I can take advantage of more than just Rangers/Pathfinders...
The armor was achieved by three stages of stippling from Regal Blue up to a 50/50 Ultramarine/Ice Blue with a Citadel Tank Brush. Time-saving warning! I primed the bottom section and top section of all the grav tanks separately (white on bottom, black on top), then painted them separately, and glued them together at the end. Made things go markedly faster and with much less cleanup.
