The nice thing about LEGO creations is that if you like someone else's, you can usually make your own copy.
Case in point: I had a friend lusting after the Arvo Brother's LEGO Polaroid MOC. With a bit of luck (and leveraging the fact I have a metric ton of brick on hand) I was able to come pretty close to duplicating their build to make a gift of it.
Trying to figure out the techniques used to make this model was a decent challenge, and I dare say I learned a few new tricks in the process.
You learn by doing, sometimes.
