I vote for Submission #4
-THEME?
The picture fits perfectly with the theme; all elements look good together: the colours, the expressions, the setting, and the characters.

- WHY do you like it?
All details of the picture fit perfectly together. The colours are mild, and I like the texture of the palm trees. It is a picture that makes me happy looking at. The background is detailed and have textures that fit each part - the sky, the earth and the grass.

- WHAT really gets your attention?
That it looks like digital art whilst being traditional.
