LoL!
The good things about learning on big projects is that you're working on the big project. The bad thing about learning on the big projects is you'll get a good way through, then your skill level will suddenly jump dramatically, and then you have to decide whether you are able to fix your old models up to your new standard/level of ability or if it will be easier to scrap it and start again.
I've lost count of the number of times that has happened now but fortunately I seem to have plateaud somewhat as skill jumps are not as drastic these days and I can probably get away with not fixing things I notice (but I do anyway because reasons).
