Thanks for the comments,
does anyone have an HDR skymap of a dark sky I could use? I'm using the cobble HDR skymap atm, since it's the only HDR skymap we have... You are correct, it doesn't match the ambiance colors of the map. Also, In the previous shot I set all fade in/out's the same for all models. These shots are with the correct fade in/outs, thats why these may not look as perfected as you so say.
About the dots on the skybox, thats my texture on my sphere model to create the moving sky.
