Been building since the 80's, won a few local competitons when I was 15 to 16 years old. Built two dioramas and dozens of cars. Time passed by and all those things were discarded.
Recently built a Millenium Falcon, added LEDS and complete weathering
I say I can build a decent model, the MPC Falcon was a nightmare to get it to fit right, its known for it. I dont know if this helps?
