Thats a fantastic army and the painting is brilliant. The vehicles are beautiful, but its the command stands that are my favourite (often the case with Epic).
lovely stuff... where are the figs from?
The AT-STs are from
Star Wars Risk: Original Trilogy Edition. I am uncertain, but I think that the TIEs are Micro Machines (like the AT-ATs, as the OP mentioned). The TIEs may be from the
Star Wars Electronic Galactic Battle game, but I tend to get the fighters from that mixed up with the Micro Machine TIEs, so I could easily be wrong there.
A number of the infantry are GW, but I dont know if they all are.
