Haven’t started Robot form yet but thought I’d give you a lookie into what I’ve done so far with Vehicle mode.

[update] started Devastator’s head and added a Decepticon symbol on the drum

 

Nice work, I'm about halfway through mine, I was 50/50 on if I should do the red and white markers on the side but after seeing yours I might give it a go.
What did you use for the tires?
I thought about a watery khaki drybrush but haven't done one before

 

Hey! Thanks for your comment (big fan of your work) for the tires it was a combination of Citadel - Armageddon dust and Karak stone, but you can’t really see the stone. I just tend to use them both anyway.

 

Not bad at all, the weathering is a nice touch and adds that dust effect.

 

Very cool! Out of curiosity, are you planning to add the Decepticon symbol on the drum?

 

Yes! Cutting it out Myself. I’ll have an update today

 

Looks like a real truck on a giant piece of cardboard.

 

Cool, thank you. I look forward to seeing robot and combined paint jobs!

EDIT
Posted this reply before i saw you post the Dev Head pics, its nice to see which parts you add red to, mine are slightly different.
I like the white detailing, i need a finer brush to do mine!

 

Thanks for the reply! I cant wait to see yours!!

 

Wow! That’s a huge compliment, thank you!

 

Added the symbol.
