Thanks! I don't use battle maps myself, so I don't know what makes a good battle map.
I feel like what you have in the glade generator is almost there, just needs to be square or rectangle format, and less dense tree placement, miscellaneous rocks, boulders, things to hide behind, climb on etc.. could even just be really simple. Anyway, whether you decide to explore battle maps or not, what you've already got are amazing resources.
