when i skipped through my folders this morning, i found this again.
so i took it a little further by tweaking the fov of the foreground hangar and adding some technical stuff on the right. still very scetchy tho and to be taken furhter.
but my direct question is (i'm too dumb these days... :P), i still having trouble with the background fog/haze. i added it to put some depth into the piece and increasing the feeling of height.
but i just can't get it right... i don't know what i'm doing wrong, i tried very long time with color correction an such, but it just does't seem to "fit in"

thx for your help everyone! :)
