Generating ideas and possibly another style

I've been doing primarily one style for quite some time, and I've always love line art, but I like other styles as well. Sketchy, raw...fun...yeah...

Today was just a small sketch to get the brain pan fired up. This is another style to pursue soon:

The concept is from something else we're [a team of very talented artists and myself] working on at the moment. Well, really, this isn't part of that work...more like an offshoot of an offshoot of an idea of a potential notion. Still fun though... lol
