ITT: We attempt to recreate original levels from nothing but memory

So, a few hours ago I got bored and decided that I would attempt to recreate part of an original IWAD level from memory and memory only. I chose the starting room of E1M1, without looking at the original level at all...



As you can see, I failed pretty hard, when I actually went back and looked at my level my palm pretty much went through my forehead and out the other side, because there were so many obvious things that weren't there. This actually helped me appreciate the game's level design a bit more, even when I already loved it.

...And that's how I got the idea for this thread. Try to recreate parts of an original IWAD level without looking back at the original map and post your results!

This has been done before...

That said, I made E1M1 and E1M3 from memory a while ago, and they were pretty accurate, but I don't remember whether I saved them or not.

Maybe if I feel frisky, I'll take another go at E1M1.

Aww, I guess I'm not as clever as I thought I was.

Well, I suppose we could resurrect the concept, couldn't we? Besides, this isn't just for E1M1.

There is also SMEDLEY, av20 from memory and Eternal Memories 1 by TimeOfDeath.
