growls extremely jealous, mine doesn't look near this good. are you using z brush by any chance? i don't think i would be able to get this detailed in maya, if i could it'd be a crapload of work, doing this myself i know how difficult and how long this thing takes, and im doing the keychain version for my class not the real thing. the bolt thing on the right side thats the main piece im missing that im trying to find images of to create a bump map.
Well texture me impressed! R2's a pretty good exercise too, enough people know what he looks like to pickup on even the slightest inconsistency- and you've definately done your research. Detail and proportion look spot on!
So, um... do you wanna see the R2 I put together? [link]
You can, but I would leave this version also..Id like to see what you can do to make it lok real..But the flat white looks very definitive and gives good clarity to the lines and the depth of the model....
