It looks like you have a really great project going!
I like a lot of your choices, one of which was to keep it red.
My only caution to you is to watch the weight. Those P-30 chassis were barely adequate to the task. IIRC, the max GVWR was between 14,000 and 16,000. In bus form that meant that if every seat was full you were pushing up against the max weight.
