Sometimes I stumble over pictures that just make me drool. This time it is by one of the talented artists over at Massive Voodoo: Raffaele Picca alias picster
His Blood Angels as on the above picture (taken from his Coolminiornot account) have exactly the style of paintjob which I would want to see on my army. Especially the Object Source Lighting (OSL) from the Plasma gun makes you want to equip every model in your army with one.
On top of that (Picture taken from his blogpost on massivevoodoo) he even has a tutorial up so that a skilled artist may even reproduce his work. Just plain awsome- pay them a visit there are also a lot of other useful tutorials up there.
