Inner Sphere Assault BattleMech
The Atlas is a 100-ton monster. So many versions to choose from...They generally mount at least one large close range and one distance weapon and a bunch of smaller medium range weapons.

This was done a long time ago. What you see is what I did. If I were to redo it, I'd do a much cooler/menacing face, now that I have better brush control. The base was filled in with sand grains. When all was set, I applied a coat of glaze to protect and seal it.
