You can also post it on TF2 Coaching Central. It's a discord server with a lot of newbies and you could put it in the self-promotion channel. People normally watch the vids there from what I've seen (also may give you interest in trying out comp 6s :) )
Some actual thoughts from watching the video:
- You might want to cut out boring bits and focus on multi-frag sequences. It seems your vids are only from actually playing the round in its entirety
- Stylizing it in a frag movie may be your best bet. Use the first bullet point and layer some music over it, mute ingame-audio in a video edtior (or at the very least, lower it to where the music is louder), and only cut to scenes with frags (or if you don't want to do cuts, just speed up portions of the video where you're not getting frags up until you get frags). People want to see frags actually happening not the time between you hitting body shots/missing before actually getting the frag. You'll lose viewer attention really quick
Also looking at your twitch stream you want to make sure your video output is taking up the entire screen. If you look back at your saved broadcasts there's some black screen space. If you need help feel free to reach out
If you're aiming to make content and grow a decent following try to follow how some other small YTers make their content for TF2. You're doing a good job to start off so find some unique video editing styles and go from there :)
