Thanks for all comments!
I have already redone this part, cos' I saw that I forgot to add some details to it and wires were messed up completely. I also have added some lines and fixed some bumps on the whhel-bay part of the panel. I have also modelled door frames. I hope that it looks better now.
Tommorow I'll start modelling rear door panel and make a basic mesh of the floor.
This time I'm also posting some wires (smoothed and usmoothed).
