A lot of times, drawn images don't have that authenticity to them that elicits a smile out of the viewer... But this picture really does.
I was poking around deviant art in a bit of an analytical mood trying to find inspiration for a story, so I was really overthinking things. When I saw this picture, it just arrested my thoughts and made me feel happy. It's stunning.
So, thank you for the beauty and the smile! You're one hell of a great artist.
