Help me take my art to the next level?

Hello! Not sure if my art belongs here, since I don't take art super seriously, but I'm looking for some feedback. I used to be very into art during covid but decided not to pursue it and took a 3 year long break. Started drawing again in December so it's definitely not as good as it should be. Never the less I'm feeling more warmed up now and want to make better drawings so some help on what I should improve on is very much appreciated! I know I could brush up on shading/lighting since that's not really my strong suit but for other things, I can't quite put a finger on what's off or missing. Artworks arranged in newest to oldest. Thanks!
