Thank you guys for your replies, sorry for not getting back sooner. Damn work gets on the way.
I actually tried to improve that painting but I didn’t get anywhere with it.
Matthew, Thank you for the over paint! That made it loads better. I tried to continue from there, but as soon as I started adding values it got ruined. I spend one whole weekend at one point trying to improve this, but got nowhere. :banghead:
Although I did learn something from all that. I’ve never thought of adding center of interest just next to the center line. It works so well, that I’m going to use that later. Cheers!
Lunatique, thanks for your reply. I actually tried to simplify things by leaving out values so that focusing on composition of shapes would be easier, but it seems like it actually made it harder. Also adding values later was very difficult for me for some reason.
You are absolutely right on all of your suggestions. I’ll get back to this when I think I understand something about composition. This will be a good test of skills 
For now, I went forward and tried central composition.
This time I added values, colors and an IDEA 
This is a self assembling city.
