Loving the tiles. And the changes to the story are cool, was it always there that you'd get to travel with Red?
Bear in mind (for going to Sinnoh) RSE took place 3 years before DPPt, and that Rowan was in Kanto for 4 years before DPPt, so you... Probably thought of that :D.
Anyways, like the look of everything, it's all really great looking. Keep up the good work!
