Anyone who does diamonds is a nutter and I salute them! Excellent looking harlequins! I may have to get back into them again eventually. Just wish they had their own codex instead of being rolled into the eldar one.
Update: Purchased some Hawk Lords decals off Aquila Relics. An A4 sheet for £25 and £4.50 postage. postage a bit pricey but there you go. Took a screenshot from their site to show here.
