Sorry for the double post, but I didn't dare to edit the last one again.
Updated 1: I've decided the names of the towns and cities in the Nishi Region, and it's gymleaders. I will come with gymleader sprites soon. I've also decided all the dungeons and big "events" you have to pass through. This is the right order from start to finish.
Tulipa Town
Beginning town. This is where you live and where you get your first pokemon of Prof. Pine
Crysanth City
Just like Cherrygrove City, just a bypass town with to get started. Some rp events will take place here.

Blizzard Mountain
A mountain full of skiers and ice pokémon. Some RP events as well.
Papaver City
The second city with a gym.

Crocus City
The last city and with the last gym.

Islands of Life
This is where the legendary bears (yes I think it will be bears) will dwell.
Update 2: I no longer need help with the naming of Candoll-evoline. The result became Candoll > Blazerina > Volqueeno. I've also updated the pokémon list in the first post with types and new names.
And here is the sprites for Candoll and Blazerina:
Update 3:
Since I wasn't happy about the Cleow sprite (it was way to big and un-cute to be a starter) I re-did it. So here is the new version:
Enjoy.
