manga head rotation fail + context

(My artwork is not the rendered work below! Those are just to give an idea of what I'm trying to achieve) Anyways I can't rotate the 'gamma' head as indicated. What I want is to rotate the head in any angle, without references (from imagination), properly (especially if it's that frieren angle). Need I specify more? If not, how can I achieve proper orientation? note: The artwork shown that is not owned by me was not used as references. I drew everything from imagination. Also, I rarely use ctrl z or an eraser to simulate traditional pen drawing, for some reason.

Kiss sketch

I'm not super experienced with drawing kisses or with people making contact in general. Would most appreciate feedback on the kiss, but overall anatomy tips would be very helpful

Captain Pirate-Man rendering

I have an artstyle that generally uses lineart for things that should be in focus. But I feel like I either can't render if I use lineart because it ends up looking weird or I just don't know how to. Does rendering work with lineart?

An Old Friend (or Foe?)

This is my first time using the feedback tool, so forgive me if I make any mistakes while using this. I drew this pic as a last-minute submission to actually complete SOMETHING. It's not pretty or neat or anywhere near completion, but the point of it to actually have something to show that I'm genuinely drawing and being more proactive on Artwod and using my skills. That having been said, my biggest hurdle right now is the sense of perspective with the umbrella. It's transparent in the original reference I have but I can't make heads or tails with it's "spokes" or whatever they're called. It's been a LONG time since I last made any sort of illustration digitally, so any advice, umbrella related or not, is highly appreciated. Thanks for the taking the time to read this and constructively critique my drawing!
