Well just adding some extra highlights to that armour would make it slightly different a good way would be with some blazing the vomit which I feel would work slightly better than using yellow. You could also use some control washes to darken anything if need as these are quite thin and won't ' goober ' it up.
Here is an example of a work in progress I am doing now, the red is done by using blazing orange and then vomit brown.
The full recipe is:
- Basecoat scab red
- Shade Scab and Black it the deepest recesses
- Then build up with scab/ blood red
- Then blood red
- Highlight blazing orange
- Highlight vomit brown
- Glaze Baal red
I will also probaly re highlight it a bit, hope that isn't too long !!! =)
