Custom parts (modified, chromed, printed, painted) tend to divide a lot of builders. Purists consider them "cheating" or somehow offensive. I'm actually pretty OK with them (at least the chromed and printed ones) mostly because I use them in animation a lot. It's hard to deny the results of a nicely assembled bit of quality chromed parts. You can't tell me the impact of this outrageous custom Harley by builder brickthebrick would be just the same with gray parts and limited official chrome, just look at that engine!
