I made a status update some months ago to this end. Reiterating for thread:
Murderous Intent (2001) - seven techbases. Too cramped, shitty implementation of difficulty.
No Hope For Life E1 (2001) - E1M3 is mine. Again, too cramped (I had a poor perception of space, I think). Way too homagey.
Doomworld Speedmapping Compilation #2 (2001) - MAP10 and WTF, this is poor. Looks okay for a speedmap of the time, plays like ass.
Doomworld Speedmapping Compilation #3 (2001) - MAP05, better than the above (kinda) and I like the traps. But why did I forget ANY health?
DoomCenter Episode 1 contest (2001) - E2M6, which I reused/edited a little for Sinister Intention. It's my map, I'll do what I want.
Sinister Intention (2012) - seven techbases (familiar? :P) in which I effectively forced pistol use against all low-tier enemies. Ugh, WHY?
100 Lines (2013) - several maps are mine, check the readme. I enjoyed this project enough to crib together my own episode.
900 Deep in the Dead (2013) - one map cribbed from the above, full E1 replacement. Am still proud of this, actually.
Switcheroom 2 (2015?) - MAP01, a mashup of sorts between the first and last maps of DOOM 2. Eh, not bad.
Nex Credo (2016) - 11 DOOM 2-styled maps, a mixed bag. Some of the better maps being used (with permission) for FreeDoom currently.
The Becoming (2017) - still being worked on (RC1 tho), but some maps here I really like. E2M5 is probably my best ever IMO.
FreeDoom (?) - On top of Nex Credo supplying some phase 2 maps, so far I have created a new C3M1 for phase 1.
Unlike some others here, there's no hesitation on my part to admit I made some poor maps back when. It's okay to me, because seeing that there's been a progression in my craft makes me feel good.
