I've made countless Portal maps, but my TF2 mapcount goes something like this:
ctf_rafts (2010 or something): Out of all of my attempts at TF2 mapping before 2011, this one is probably my favorite.
cp_gulch (February 2011): Attempted this map for the first asymmetric CP contest. I only finished a2 of the first stage before dropping out. This was mostly because I was too afraid to participate in any playtests. Owly thanked my resignation post, which I appreciate to this day.
ctf_breeze (July 2011): My only "finished" TF2 map, it's basically a simpler version of 2fort, made while listening to several Alison Krauss albums. Mid was received quite poorly, but Rexy encouraged me to keep working on my mapping.
At some point I made a Payload map for the Build-Around-The-Track contest, but I no longer have any evidence of its existence.
koth_numbers (July 2012): Made for the star_ highlander koth contest, the map was inspired by Cold War Number Stations, so the mid point was a big hydro dish, naturally. It was okay I guess. Very simple, just like my previous TF2 maps. At least I had fun on the TF2M Highlander Team!
Melvineer recorded some gameplay of it, miraculously.
plr_dugout (January 2012): This was a PLR map I attempted for the dynamic PL/PLR contest. Didn't quite work out.
This is the only screenshot I have left of it. (Which was also the thread screen.)
koth_amazing (July 2013): Over a year after I posted that I would be re-working koth_numbers, I finally delivered with koth_amazing. It only has slight similarities to Numbers, the main carry over being the linear, rectangular layout. I'll finish it someday, probably.
Here's some gameplay footage.
cp_clover (January 2014): I made a spawn room and then got bored. It's too bad I don't have the drawing AyesDyef made me.
I'm skipping Doge 1, 2, and 3.
ctf_dauphin (August 2014/July 2016): I started this map in 2014, but didn't release it until 2016 due to medical complications. I'm hoping to finish it at some point, with the aid of many Frontline assets.
ctf_banja (July 2015): Just a week after a major surgery and still under the influence of heavy anesthetics, I decided to start mapping again! This time, my goal was to make a map layout using only prop fences. Did I mention that I was high as balls while making this map? Like, I designed the whole layout using only prop fences. Just ask Chin.
ctf_norfolks_bathroom (August 2016): Made for 7.2 hour contest I think. Norfolk helped me out by sending pictures of his bathroom. The result is a map centered around a giant pee filled toilet thing. It's pretty self explanatory.
And that's it! As you can see, even with 9 TF2 maps under my belt, I still have yet to achieve success. At least I have veteran status.
