Toshinho Stone Freeze Color

The first color work, that I've done in iPad, and I'm actually proud off!
Aside from the shadow on the ground (wich was a 'detail' I tottaly forgot), it was all done on iPad Skecthbook - free edition. I finally defined what brushes to use depending on purpose or need. I still have a long way to go, but I think I'm on the right direction... I hope.
For the color choice, red and green are in fact my national flag colors (Portugal) but I didn't do because I was felling patriotic... it was pure chance.
Lines by: - This guy add/has a MILLION more talent than me, but he stoped drawing some time ago (I think) because he couldn't make a life out of it... very sad.
Colors by: me.
