I love science fiction, but haven't done much art work with tech/mech elements.  So I think I'll try working up the giant robot.

Ive been watching the great instructional videos from UTube on creating concept art.  Especially Feng Zhu.  Check him out on http://www.fengzhudesign.com/.
They all recommend doing little monochromatic gestural sketches to work up ideas. Leonardo used to do this as well.  So I'm giving it a try.

I watched Joe Bluhm (http://joebluhm.blogspot.com/) do a dog caricature on UTube. I was also inspired by the way Wallace Tripp does animal cartoons.

Can't forget 'ol Mitt.  He's getting more colorful too.

Newt becomes even more colorful

Taking a break from drawing a face allows you to see it more clearly when you come back to it.  Meanwhile, more practice drawing cutesy cartoon girls.
