Nice! I just found out this figure existed and am planning on doing a similar thing to you with some washes and chrome drybrush.
after seeing the great job elvis did with his over in the custom section ,i thought id have a go myself ,my skill set is nowhere near elvis,s but im pretty happy with it so far ,it was more work than i thought it would be but i had fun doing it
almost finished just need bicep bands and buckles added to belt but here he is
started out with a 13 inch dcd hero upper body and a mattel 12 inch movie masters superman the movie lower body hybrid ,bulky upper and legs slim enough to take the armour ,hot toys zod body suit painted grey and a 12 inch mattel multiverse armoured bats
cut and dremeled the bats into the various armour parts boots gloves etc ,repainted and assembled him ,added new belt and cape added extra wrist articulation ,pretty pleased how he turned out ,not sure if ill add light up eyes to this one ,i like him as is at the moment ,i like the extra bulk and heft and texture separation of the batsuit under the armour ,that the full plastic figure did not have
"tell me do you bleed "
you will if your not careful with that dremel lol
it was a lot of work hollowing it out thin enough so it fit right and looked right ,not sure i managed that part lol
"shes with me now "lol
here he is with slightly repainted wonder woman ,waiting for my nephew to sort the eyes out for me lol with the buckle added to the belt
