I just edited your pictures with paint, and it looks really bad but it gets my point across.
I hope you don't mind?
I made 1 resembling my description, and I made 3 other just random ones. Basically, all I'm trying to express is that yours is...; very.. boring?
Its just a bunch of squares, the ones I made from yours allow for alot of planning or alot of random attacking. Wichever suits you
Although, i think it'd favor the planners^
Oh, and I guess you'd probably need to change the value of owning all of 1 color.
Of course, this is still your idea..; and if you want me to remove the picture consider it done. It doesn'thave to be here
Also, feel free to branch off from my idea.. Doesn't bother me any, I'd actually be sorta flattered
