oh no you're 20 and your life is over...
I'm 21 so I must be really fucked.
You did a solid job on that cave-thingy and you seem like a pretty crafty guy. I wouldn't worry one bit, just keep improving man.
Don't know your current work situation but try to find the time where you can and try to stay motivated. Try to find projects/idea that interest you, that'll help a lot. I tried to make a L4D2-map during the six month hiatus I just had and, to quote Guillermo del Toro, it was like "fucking without a boner". Don't recommend it!
It's good that you've joined us here anyway mate, we're always behind you ![]()
