This is one of the Cougar variant mechs from the "Border Break" series of models. The models are based on an arcade game of the same name.
Last night I painted the head and torso. Experimented with doing a wash for the first time to make it look worn and dirty. I like the results for a first attempt. I did manage to mess up part of the back and I will have to re-paint it
Took this picture with my I-phone 4 and the HDR Fusion camera app.
