New finished piece, and somethign strange

Hello folks!
Finally a finished, fully rendered Artwork.
This one took me quite a while. about.. 10 h I guess, stretched over several weekends, due to i have  a tone to do for work @.@

well. A while ago, since i got my new Screen,  i encountered a. lets say problem.
As my artworks looked  as i want them to look during I showed them in photoshop, as soon as I saved them as JPG file and viewer them  in the picture viewer or in a browser, they got heavylie oversaturated. I researced,  tryed out, and as i set the settings of photoshop to " monitor" i finally saw them how they really where. ok,  problem fixed I thought...
but,  as I saved them again, they where  sightly oversaturated agein.
the solution there: I disabled the option:  convert to s-rgb in the save for web and divices menu. Well.. bit i still feel, i did something wrong oO maybe someone can tell me how to ajust the options in photoshop, so that i  see what is really there, and dont get the surprise that everything is  extreeeemly oversaturated,  hen i finished something...

Well, for an example I show you the new picture first in none srgb and then in rgb. if you see a difference, it would be nice to mention it in a comment.

so here we go!

none srgb

and the srgb one

As a note: my working - monitor is an Eizo S2433W  and i  calibrated it with a Syder 3 Elite.

Hope you like the picture, and maybe help me out :D
