It would be nice if you can bring up the white of the clouds by duplicating the earth and changing the blending mode so that the planet is rainbow but the clouds stay white. This just looks like a gradient layer over the planet.

Nice idea, great looking image.... nice job

good mehendi design but you need to upload ur own image(the image of the hands) uncut on ur sbs !! well i like it but it will be more better if you can make the colors only on the mehendi design not on the skin okey G- luck author

It will also look better if the colors blend better and don't look so "stripey."
Great concept, though!

Remove the color overlay from the skin and this will be better.

Try bending the colors with the curves of the arms, the are overlayed now and do not really look convincing to me

This is great...but I think I would have almost liked this more if the edges of color weren't so obvious. A bit softer transition from one color to the next. I realize it's past the editing period, author...so let me just say..."nicely done"!
