He didn't even ask yet......
First up Big Red got a magic wash of 2 parts GW brown too 3 parts GW red ink over all red areas. (save unused wash)
Once dry the muscled areas were painted with 1 part Vallejo gore red to 3 parts Ral Partha red.
1st highlight RP red this time start adding subtle ripples to the muscles.
2nd highlight 3 parts RP red to 1 part VP orange fire (GW fiery orange equiv)
3rd highlight 3 parts RP red to 2 part VP orange fire
4th highlight 1 part RP red to 1 part VP orange fire
5th highlight 1 part RP red to 3 part VP orange fire
Add 3 drops of magic wash mix with an eye dropper to the original wash. Then reapply the wash to the red areas this will help create a naturally blended color to the red. Make sure this last wash does not puddle, look behind his right knee it puddled there.
