Surround Speaker Placement???

Note sure whether to post here or the Speaker forum, please move if needed.

Is it OK to have your surrounds offset from the main listening position? As you can see in my gallery, I have my 2 surrounds back behind the main listening position. I know they are supposed to be on the same "plane" of that listening position and not directly behind it. I can't move the left surround up because it will kind of block the front of the sliding glass door into the backyard. As you can see in the pics below, I did move the right one up to be on the same plane and the listening position. So, again, is this OK, or not a good idea?
