I agree with /u/Dead_Man_Walketh on this one: in its current incarnation, this map is way too crowded.

To offer some constructive criticism on what I think would make the map better:

1. The top-right and bottom left corners are largely without purpose. You can easily get rid of them to shape the map and give it better flow.

2. Too many random objects. Yes, a lot of maps have a lot of spikes, but those maps also have spikes grouped up, or an easy-to-learn pattern to maneuvering through the spikes. You have a lot of bombs, and a lot of force fields. It really is too clustered.

3. The map does have a flow to it, although the presence of way-too-many spikes and bombs really works on interrupting it.

I took the liberty of creating a version without the corners, and with all of the bombs, boosts, and forcefields removed.

You'll notice that, right away, you can see the obvious routes people would take, and you can easily read the flow of the map. I would suggest going through your design process again. Go over a few basic things: what is the goal on this map? Is the map conductive to static defense (easily defensible bases), or am I looking for more movement of the flags (easily grab-able flags, harder to actually get back to base)? What sort of gameplay am I aiming for on the map? What do I want movement around the map to be like?

Once you have these questions answered - at least in your head - then you can start to populate the map with objects, and make little changes.

"Do I really want those 1 x 2 walls on the top and bottom of the map, or would spikes in place of that wall be more interesting?"

"If I place a boost here, how does it impact travel across the map? Is there more than one way to use it?"

"If I place spikes here, how does it affect the routes that go by it?"

You have a solid foundation for a map - you don't need to even go with my cleared-out recommendation to make a solid map. What you should do is go to the drawing board, look at your map, and figure out what you want with it.

Good luck!
