The two custom regions already on the site seem to be enough. Threads barely ever make their way to the custom regions, so I doubt there will be much activity on it, and I find it rather pointless to add this as a third.
On top of that, this is a whole new region. Location is very unacceptable, please actually be specific and descriptive with it. In pretty much every region, there are many more notable places other than the 8 gyms, in order for it to be more authentic, consider adding them. The landscape lacks detail as well. Sinnoh has an icy and snow packed town, but not all towns are like that. Routes and towns differ from place to place, what kind of trainer wants to explore a region that is the same no matter where they are? Make it more different depending on the area, environment, ect.
Speaking of area, there can't be towns without names. Sure there is a dot for each, but they need to be named as well. Also, history is very unacceptable as well. An entire region can't be summed up in mearly a few words. Even if not much is known of it, it is inhabited. You can tell the history of the native Pokemon and people, how it was discovered, technological advancements, ect.
I do not believe another region should be made, but if you make these corrections, perhaps the staff may find it fit to consider it.
