Famous Characters by Josh Sumamana
I always impressed about artists that get to make illustrations about famous characters, it's really fun to see their personal touch on their versions. I stumbled on the work of Josh Summana while wandering through DeviantArt galleries and I gotta say I'm still quite impressed with the level of detail and with the style of the versions he made.
I also posted two videos of the process he did to create his illustrations, hope you guys catch some ideas from it. You can see more awesomeness from Josh at his DevianArt profile.
