My first level design idea (Hand Drawn)

I drew a design idea for my multi-player map and to be honest I'm quite happy how it looks its quiet balanced with space/area for let’s say (sniper classes) for long range a class for mid-range and close range combat.
I really want the player to not lose interest in the map by making it feel competitive and challenging. The main things I want to achieve by making this map is the aspect of no camping, no higher player/class advantages. I want the map where a new player (n00b) and advance player has the same fair advantage over each other by knowing how to navigate the map easily.
I will create a photo shopped version of my map with detailed path, scenery, buildings and second floor ramps and buildings.
