Sculpting a member of the HazMat team

Well I have decided for my first figure(s) to sculpt someone wearing a HazMat Suit. Its slow going building up layer upon layer of the greenstuff. Heres what I have so far. I stil have work to do smoothing out the suit and finishing the arms and adding hands, along with some other minor details that I plan on adding.

The pose will be the guy holding up his left hand to signal the rest of the team behing him to stop, while he checks the readings of his PDA/Meter/Gieger Counter that he will be holding in the right hand. I have sculpted a tab to the bottom of his feet so he can fit on a Slotted base easily. My biggest holdup is figuring out how/what to sculpt for the gadget he will be holding.

Depending on how this one turns out I am planning on sculpting a couple more HazMat team members (unarmed) and maybe one armed team member. If the do turn out I don't have any plans at this time of getting them cast up, though if I did I would probably be casting them myself out of resin.
