>>8966991>Painting partsFine if it's a mask that isn't available in another color AND it doesn't look like shit. Painting any other parts is unnecessary.
>Cutting partsBad, unless it's flex tubes which are meant to be cut anyway
>Using 3D printed partsFine, better if they actually look GOOD. We're not quite at the point of 3D printing that perfectly replicates the look of official parts, but we're getting there
>Using non-Lego partsSame as above, fine if they look good and match the aesthetic
>Using CCBS>Not using CCBSIt's a system made to be compatible with technic parts so there's no reason not to use it if you want to. Can look good or bad depending on its use
>Greebling with system partsFine for a few small details or to add extra articulation/support. If you overdo it and have a MOC that's like 80% system greeblshit it looks bad
>Putting boobs on your moc>Putting dicks on your mocCoomer shit is automatically retarded and most mocs made by cumbrains look awful
>Using illegal connectionsBad, you're just going to stress/break your parts
>Using rubber bandsFine for adding technic functions or for certain details
>Using misprints or rare partsBetter for it to go to good use than sit in a box somewhere
TL;DR: everything is fine as long as you aren't breaking anything and it doesn't look retarded
