The Energon Pub

Hi, I'm new to customizing but I don't know where to start... :S

well I was thinking to do either a classics version of Rotorstorm or Gobots Warpath using HFTD Tomahawk. The problem is I dunno which head to use for him.

Another thing is I don't actually like the feet (the insect looking toe-thingies) and I thought to change them and attach new ones from the pin where the lack part is attached to the shin, but yet again I'm quite lost what to use...

Can someone guide me what to use please?
