You definitely have the right mindset... on average people don't spend quite enough time refining their playlists (I'm due for an update myself).
But I am not sure the forums is the best place to promote playlists.
We are all hear to help each other grow in knowledge but this isn't going to be the place that anybody grows their subscriber base via self-promotion. If someone here likes your work they will subscribe and will likely binge-watch your playlists from YT itself, with very little actual need to have had the playlist featured on these forums.
