Help with Control room layout please!!!!

Well it's been a year long reno and our studio is now at the drywall stage.. I have a question to ask that I need some help with. It involves our control room. it is 11x12 with a 4x7 foot window in it that looks into the love room. on the south wall is a main sprinkler pipe that has been boxed in and there were 2 pipes on the west wall (above the window) that was boxed in as well with angle and studs and drywall. Looks great!! BUT a buddy of mine has said that the sound will not be right in the contol room when we go to mixing and stuff.. Is this true? He says because all the walls are not the same.. What is the easiest and cheapest solution to fix this problem if it is a problem. Thanks for all your help. Also I hope I posted this in the right spot.. Chow for now.. I will be posting pics soon of the complete reno as well Dezi Gebel Layin Trax Recording Studio Ingersoll, Ontario CANADA

Here are some photos of the room.. Let me know what you think we might need to do...

I'm having a hart time following you... The walls not being the same? Which walls, or is it the ceiling? Do you have a print you can post?

Ya sorry the ceiling.. It has 2 bulk head on it. One on the west wall over the window and the other on the South Wall...
