R4 concept

Hi there! After the last job and becouse of the really boring lessons (see the previous post) I've been thinking to something to not just waste my time.. so I ended up thinking about this robot and a whole story connected to him.

Here's the first concept for R4.. the texturing is made as a "matte painting", so it still isn't part of the model itself (I still have to prepare the UVs), but up to now it's enough to understand which will be the next improvements needed. As Giulio suggested, I'll have to work on the details of the rust, especially along edges.. hope bumps will help :)

I will be posting some news about this guy soon.
Hope you enjoy!

P.S: Don't be shy. Every comment is welcome!
