And the head is done! Well, the hard part anyway. Hardly used any of the epoxy putty leaving quite a bit for possible future projects (unmasked Wasp head and gun perhaps?). Not sure why but the added moulded details looks a bit dodgey in these photo's, in real life they're smooth as silk! Really pleased with the results I achieved here. The last photo is of his new head but showing close to how he'll look when painted.

Steps taken last night:
1. Chop off Bumblebee's horns and mohawke
2. Thoroughly wash Bumblebee's head in soapy water
3. Sand entire head with P1000 sandpaper
4. Using epoxy putty, sculpt antenna thingies by rolling a small section out in a sausage shape, position on Bumblebee's head then gently blend the edges into the plastic using a gateaux fork
5. Leave putty to set overnight

Steps taken this morning:
1. Make antenna thingies symmetrical using P400 sandpaper (don't have a file unfortunately) then smooth it all down with P1000 sandpaper.
2. Take a 0.5cm2 ball of epoxy putty and fashion it into the shape of Wasp's unique jaw
3. Leave for 6 hours until the putty has set then sandpaper as above.

Note: For those wanting to try out the epoxy putty, keep a jar/glass of water nearby as you'll need to occassionally dip your fingers in it get the moulding as smooth as possible - that and it's just too damn sticky to handle if you don't!
