Agents of the Imperium - Expeditionary Navigator painted

I was getting a little weary of painting crimson, so over the last few mornings I've worked on Fortunato Locarno instead! He's going to be part of my Thousand Sons force so I needed to tie him in thematically, but I wanted him to have a contrasting color scheme - Good ol' Tzeentchian blue and yellow it is, then!

  

House Locarno assigned Fortunato to the XV Legion in the early days of the Great Crusade and he served with distinction, showing an almost preternatural ability to guide the Thousand Sons vessels to their destinations swiftly and unerringly. Afforded training by the Corvidae Cult, he gained unprecedented prognosticative powers, however in later years dark whispers that his abilities were enhanced via dark pacts with servants of the Architect of Fate proved to be all too true...

I'm not completely happy with his shoulder weasels (which thanks to Dave Taylor, I can't get out of my head). I wanted to go with the blue-white similar to that found on the Sons and the Spireguard, but I'm not fond of how the spots turned out. Not sure how to save it without overly gumming up the details with overpainting, though. Hrm...
