So I'll follow Jonathan with one portrait a day, but i'll keep with one more rule... I'll take only ~1h to finish sculpts, so it will be more like speedsculpting etc. As far as i know myself i'll be bored after week :D but i'll do my best to not give up.
So I'll start with this guy made in 3D-Coat. Most of time i've used voxel sculpting and at the end i've switched to surface to make some edges sharper.
