Really needs to be Downloaded at full size to be appreciated. Very good job incorporating various imagery into a whole piece. Everything connects seamlessly except maybe the hugeness of the butterflies, and it's a dream, so that's covered.
So, did you create the grassy hillside? It doesn't seem to be credited
The planet Earth, emerging from the clouds up in the sky, detracts from the rest of the picture. It draws the eye and makes the surreal images of the butterflies seem less fantastic and wondrous by comparison. Also, the planet is very clear and in focus, suggesting that that will be the next place we'd be going. It's kind of sad because the hillside looks like a place I'd like to linger on.
A "real-life" image can mean different things to different people. Dreams are wonderful things, but are also extremely personal. Is this your dream? The fox's dream? A god's? Someone else's? The identity of the dreamer is one of the most important elements and it's missing.
This is truly a beautiful scene; I'm sorry if this seems too critical.
