I love how you made his/her grin. He/she looks so content with the world. I wish i was.... This is a very good advertisement to the world (if if unintended). I mean come on, who's just happy with themselves, some grass and the sun and to top it off its a griffon which makes this a 6 star drawing (if only we could have that many stars).
True beauty. A little empty, but that seems to fit it quite well. Overall I have no negative comment for you. Positive however, I have only one. I can't wait to see what else you can do.
I really like it, I think its peaceful and pretty. I think you did a great job! :P
