I actually intended for the colours to be cold.  The decision was partly out of preference and partly to make the scene seem cold.  After all, it's gotta be a bit chilly at that altitude.  I do appreciate you taking the time to tweak to colours like that, though.  Perhaps I'll try working with some warmer colours in the future.

I feel colors are way too cold

edited here in 22 colors and tweaked colors a bit.

I also like floating island and I find this quite good ;D

(The sky should be worked more)

@Spectrum-Star - Thanks!!! this realy cool programe, it's very simple and in my language :D you really help me, thanks again man! :D

@DirtyPig - I use Paint.net.  It's not designed for pixel art, but it's really straight forward and has all the tools you need.

@bittersweet_batty - Thank you!  I did indeed leave a bit of the sky empty on purpose.  Partially to keep attention on the island, and a bit in order to highlight how empty the surrounding sky is, securing it as an analog for the ocean.

I wanna ask, in which one program i can do pixelart althought a bit like this? help me guys? i search in net some clues about it but it's hard, anyway for me ;d

I see you ;)

Nicely done! The bottom left corner might feel a bit empty, but that might be intentional. I like the rock and mountain shading in particular, and the clouds overlapping the islands came out really well.

I feel like the sky behind the island is abit too dark, but apart from that a lovely island.
