Fun Nijiyamaru Concept Art

I work part time at a Japanese convenient store called Nijiya. Apparantly, this company actually has a mascot named Nijiyamaru. Except....he only exists as a name. So I made some fun doodles at work and scanned them into my laptop and finished it in Flash. These aren't seriously going to be considered (unfortunately). But it was a fun making these wacky concepts up. When I showed them to my co-workers, a lot of them voted for the frog. Which one do you like best?

Landscape Practice

Just learning/practicing more Photoshop and a bit of Color Theory.
I followed along this really neat tutorial from Digital Tutors called "Light and Color Study: Night Scene"
Here is the link if anyone is interested (the small drawback is you or a friend have to be subscribed to this site)

I've really learned a lot from this. Hope to draw more and improve my digital art skills.
