ive had a video recommended so you might be getting through, tho I see you have subs so I suspect your channel was flagged for something in the past or people are just skipping your videos in their feed because they see no appeal in them.
Looks too timid and stock? Most "maker" youtubers seem to have larger than life personalities or personas that go with their fantastical and impressive builds. The big ones like hacksmith, collin furze, adam savage, etc. All speak for themselves. But even monotone Peter Sripol has an engaging presence with his dry humor, witt, and dare devilish charisma. I'm just saying I see a lot of "stray" in this and not a whole lot of "Hydra" or "Blade". You've got that uniqueness in you. Let it out!
Interesting feed back. Tho those builders that you mentioned sometimes can be seen like too lound, obnoxcious and/or fake... at least to me😅. Tho we all have our preferemces
