Just a repaint of the original Wall-e figure. It looked too clean and plastic, so I disassembled him (beyond the stock disassembly), put down a coat of primer (Games Workshop Chaos Black) on all the 'metal' parts and gave him a good dry-brushing with GW Boltgun Metal and highlighted w/GW Mithril Silver. After that I added some brown and yellow 'dirtying' all over and gave some areas a black/brown wash.
Much better than the original figure, if I do say so myself. (I even repainted the neck yellow, so it's more movie accurate)
