Remote window roll down

Any one see any problems with this set up? This is how i am considering making my windows roll down by remote. Since my car alread has a Power Window Control Module (94 honda del Sol), i didn't see the point in adding another one (Power Window Module). I just wondered if anyone can see an obvious problem that i do not. thanks (all of the relays are necessary isolate the +12 legs so that when i use the window switch in the car it won't roll all 3 windows down, if that is clear enough to understand)
