Just a minor update, more about brightness and colour mood on floor and walls. Not that sure about the colours, needing perhaps a few accents… (the amount of black outlines isnt refined yet)

@ Quadart: You gave me at lot to think about. Especially your thoughts about my black lines are leading to a more conscious usage. Worked out the mans head to show what i have in mind on all characters concerning contrast, saturation, and the amount of black.(eyes and hair will need some improvements though)
Concerning your suggestions about composition: Instead of just saying something like thanks, ill work on it and changing then nothing, id like to give my reasons when i dont agree - especially to an experienced artist as you are, whose opinion i most appreciate.
The perspective correction i probably wont apply, because it feels unnatural in my eyes. Items would look distorted imo and the whole mood would get an other step further toward sterility. Personally im trying to avoid perspective corrections when ever possible, even if seeing it getting widely popular since easily applicable in CG. So one could call me a denier on a related note.
The placement of the table is rather difficult and certainly debatable. It will heavily affect the density of the scenery and the weight of the main subject. I cant push it more toward the stove - it would attack my actors together with all the items on the table, making them also looking framed. They need imo a little space to breathe, even if going for a very busy set-up. Ill probably change the position of some of the items there to not look like placed around the characters. So the single shoe looking out of the skirt is staying a random element… (btw: i also believe that cutting that lady twice would push the other maid too obviously into the main actor role, which id like to keep a little more subtle)
Noticed your other suggestion while studying your paintover to get the pigling more horizontal. The maid at right is intentionally quite a lot smaller to have the wood plate tilted to the viewer and the pigling more visible. Some decoration around the poor thing will follow (ill have to be careful to have no easily rolling stuff there).
Hope you dont mind my arguing. Thanks a lot again for the food for thoughts! 
cheers
