Guess it´s time to start my entry aswell! I don´t have a concept as I am a stubborn fool who never learns from my mistakes. But I am doing a Norm Warlord, heavily inspired by the Diablo 3 Barbarian concepts.
Here´s the basemesh I created, tried a new technique when modelling this, I basically extruded the major musclegroups outward slightly, then smoothed the extrusion. I like the result and I fould it gave me more control over my sculpt than a "regular" basemesh would have done.
And here´s where I am with the sculpting atm, as you can see I havent really touched the hamstrings, buttocks and lower legs yet.
