Sketching in a cup

I've been gone for a week and yes, been doing another random stuff, sketching some doodles in the cups (Note: This is the first cup I've tried to sketch, Im working on some other cups)

Yep, this looks like a little bit childish, and colorful, haha, made them with colored pencils. 

And this is the other side of the cup.

Haha, looks childish huh? Well Im still young :D haha

I know there are many more other artists that are much better than me, but I am still proud of it :D its my work :D haha

As of now, Im working on some other cups to add on my collection.
