There's a lot of detail on the right mandible so I break it up into 2 sections. Here's the upper section. I also included a shot showing how I build the detail.
The right mandible is finished now.
The helmet is really close to its final appearance. I just need to do the weathering stages, but first I'll work on the ears.
The RF ear is in work. The lower piece is finished and the black arch has been airbrushed onto the ear cap. I'll let this dry for a day before masking it for the white arch.
I sculpted the "crack repair" with some Vallejo putty to give it some dimensionality. Here it is all painted. I used a little clear orange to simulate the epoxy that oozed out during the repair.
