Puddnhead is the 'secret' identity that artist Kevin Llewelyn uses for his commercial work. But both his commercial work and his personal work are amazing and worth checking out. He is an amazing figure and creature artist and I love his use of colour. Be warned though his work is dark, offbeat and are almost exclusively NSFW.
If you want to see more of Kevin's work then take a peak at his website. If you want a walk on the weirder darker side, Puddnhead's website is offline at the moment, but he has a profile and is often found on ConceptArt.org. Gnomon Workshop also sell DVDs from Puddnhead where he walks through his process from start to finish.
