First it looks great!
Paint's not my forte, but I have confidence in your judgment, so both rim's colored the same. I don't like the silver and black rims together so I'm not a fan of silver and blue on the wheels either. Wider tire I'm all over it for this bikes bad boy style, if both width and diameter will fit up in the frame. Bigger is better. Heck yeah fender less! Though I like the bobber fender if it were painted to match the frame, with bamboo flair.
Imagine the saddle slammed, seat tube shortened a lot, and the saddle post laid back a little. It could be mounted with a small "solo" biker saddle and springs. Great easy rider position with pegs, I mean pedals, forward pedal extension should still look and feel good and be comfortable. That's just me. I love the way you build 'cause they all turn out lovely.
