Leaving the engine compartment as is without detail

To each his own, just saying I would never paint a compartment black unless its a black car. Yeah it can look ok if done right. By right I mean prepping and masking everything. Dont be the guy who spray paints the wiring harness and everything else in the way. Seen many cars like this at car shows that look awesome until you look under the hood.
Yeah that blue car has some nice patina. Sometimes just a little elbow grease is perfect for a driver. My driver 340 sport looks like Joe Dirts car. Its just as fun to drive as a restored car.
