Peter Petrelli is going to explode. Seriously. That's how hot he is.
I used the Entertainment Weekly cover feat. Peter, Mohinder, and Parkman as the base for this. I traced the outline, layed down different shades of gray to distinguish each area, and then dodged/burned to add shading. After that, I added a Gaussian blur to that layer to smooth it out even more and then added color layers over the top, adjusting the transparency to get it to the right level. The bg was just orange, but I dodged/burned again to make it pretty
Another experiment, this style somewhat, ok, seriously, copying the one that Jason Badower explained on his blog.
