It's really beaufiful and serene. I like how you did the sun. It harmonise nicely with the phoenix. And without other birds gathering around him and looking up to him, picture wouldn't be the same. I would happily put something like that on my wall if I could
That's very nice, though the colors could be more vivid and I perhaps it could look better if all the branches were a little bit lower leaving more space above. Anyway I like the picture and I'm glad that the theme is interesting, the meaning could be understood differently.
This reminds me of something I saw on YouTube--I think it's called "For the Birds," by Pixar. There are a bunch of chirpy little birds sitting on a wire, and suddenly, a large and very different bird appears, and sits right in the middle of them. The little birds in this look curious and interested, though; the birds in the video were not too pleased.
Anyway, I like it a lot! It has a lovely evening feel, with the colours.
