that's some hot freehand work. My prof in college Durwin Talon (writer of Panel Discussions and Comics Above Ground ) uses freehand exclusively for all his illustrations. I even took a freehand class with him where i used freehand for evil (illustrating my old business card) You can get some hot results with that program. I find it a lot easier to use and more versatile for illustration than Illustrator. There seems to be a lot of fun stylized vector illustrations everywhere nowdays. If you can use it to come up with something trully distinct you'd be very successful.
