I find the palm tree a bit distracting, it's quite dark in comparison to the rest of the piece so it keeps catching my eye when I look at it >_< And I would've thought the leaves would be bigger if the tree was that close unless it's in a sort of upside-down J shape- if you edit it at all, maybe have a look at what it would be like without the palm tree there? Apart from that though, I think your piece looks awesome!
I'm having some trouble reading that orb in the top left, i can't tell if you want it to come forward or go back in space. And the clouds seem very rough in contrast to the figure, try using some bigger broader strokes to give them a more solid but whipsy feeling. Cool stuff though.
This is a great piece, really inspiring- I'm sure you have a story behind it (and if not...well thanks for the intrigue) Love the painterly quality of the organics and the smooth precision of the tec. Very well done.
