I'm working on my Mazdamundi and have used an old Steg for Zlaaq (the base is not done, just basecoated): And here's my Oldblood on foot, have a Carnosaur in progress at the moment...
I really like the scales on the steg, especially the red and green ones on his head. I don't think the pattern above them has really worked... But thats just my opinion, I'm not really sure what I would do to it. A bit more subtle colour changes with more layers maybe? Overall he should standout really well though. The oldblood looks great, really like how both his skin and scales came out. Nice work!
