Very interesting dithering and use of colors, I like this :)

 thank you!

 Warmed my heart :) Voted.

 thanks!

 Hey that's better :)

I'm liking this!

 I tried making the fish look more jealous because it is unhappy with a frowny face while the dragon has a smug smile. Thanks for letting me know though, the expression might be hard to read since the fish is smaller, maybe ill do something about that.

 thank you!

 The fish looks more perturbed, than envious, maybe it's just me, lol. 

 hmm, alright. I felt like it was happening but wasn't really sure myself. Thanks for telling me. I might just redo all the scales...Are there any particular parts worse than other parts or just all over (on the serpent)?

 The dithering seems rather hit and miss. It gives the fish an appropriately scaly texture, but looks a cluttered, distracting mess on the serpent.

Very nice atmosphere, its very calm. 

 Yay, now it's working ( i guess sedgemonkey got it fixed), thanks.

Try reuploading the file (through the edit menu).

 Pancakiosis alert.

Although the preview looks nice.

 I'm using Safari and it is also flat.

The preview looks great so far (big file isn't working for me neither), but some AA could improve this piece.

:s hay que avisar a los moderadores... no es la primera pieza que veo con este problema .

It looks like something to do either with PJ or the browser (@The Fry Bat, if your's was also Firefox) as clicking on the image will display the full image.

 Is it just my browser, or does this piece look like it's been run over by a steamroller?
