Showcase: Chapter Master Lazerian

This is one of my older projects, an Imperial Fists Chapter Master. Lazerian was done as a commission piece, one of several done for the Tempus Fugitives 'Age of Apostacy' campaign weekend a few years back. The Fugitives were operating out of our local GW at the time (a few of them still are), and when the campaign weekend went into its planning stages it was decided that they wanted a set of special character models that could be used at different points during the weekend. Some of the veterans at the store were asked if they would like to model and paint these characters, and I was lucky enough to be asked to do two of them; Chapter Master Lazerian, of the Imperial Fists chapter, and Gaius Walkenen, commander of the Dimmamar PDF... I may post pics of him at a later date.
As a base for the model, I used the gorgeous Captain Lysander model... it's one of those hero models that's just a joy to paint. To the basic kit I added a banner and power fist from the plastic terminator kit, and a ForgeWorld rhino door (with appropriate logo, obviously!).
Now, this was painted in the pre-foundation paints era, so approaching the yellow armour was something of a challenge for me (it's not an easy colour, I wanted it to look as good as possible). I tried a technique I found in GW's How To Paint Citadel Miniatures... basically, you water down the paint with ink instead of water. This allows you to thin the paint, while not losing any of the pigmentation. I started with Golden Yellow, mixed with red and yellow inks, before highlighting with first Golden Yellow/Yellow Ink, then Sunburst Yellow/Yellow Ink. Bleached Bone was added for the later highlight stages.
The marble effect on the shield is tricky, but with practice has become one of my signiature painting effects. I start with Fortress Grey, then paint over this in four or five stages, adding more Skull White with each layer, until the mix is almost pure Skull White... start with thick bands, leaving thinner stripes of Fortress Grey in between, then highlight each of those thicker segments of colour in increasingly narrow strips (if that makes sense?). Once that's done, I add very thin 'veins', running in roughly the same direction as the striping; these are a mixture of Fortress Grey and Enchanted Blue. Finally, a very thin glaze of Skull White is applied to the whole surface. There are probably much easier ways, but it works for me!
Enjoy the pics, any and all comments are welcome!
