I've gotten some more work done today on the Mantis Warrior Space Marine. There's still a lot to do, but he's getting there in terms of what he'll look like in the end (well, except for the weathering and battle damage that I'm planning to on applying).
And here's a picture taken outside during the day to give you an idea of what the colours are like in good lighting conditions!
I'm really enjoying painting this colour scheme, it's definitely less of a chore compared to the Imperial Fist armour! If I get bored with one section of the model, I can switch to another and continue like that until it's finished, which is great! Hopefully I'll get him finished by mid-week, when I'll post another update.
