Welcome. I wasn't as far along as you and decided it was time to shave it off so my suggestion is to go for it.
I didn't think your skull looked strange, I thought the black squiggles over your eyes looked strange

but I see it cleared up in the latest picture. I think you'll be happier if you go for the end game instead of worrying what you'll look like.
You worry too much, don't be too hard on yourself. You have a good head for the bald look. If it is baby steps you want, then I am all for it. Good luck on the journey to become sly.
I vote for shaving it down slick...you'll be thrilled at the feeling.
Dude,
You have a great head. Go for it! You will be glad you did. You will look great!
Nothing wrong with your head. You'll look awesome bald! Go for it!
As a matter of fact, nobody has a perfect round head. But in most cases the minor flaws don't affect the look. I don't mind the small lumps I have. The sensation of being smooth is better than anything.
Give yourself a try.
Go for it. You will love it. Give it 30 days. If you don.'t like the look it will grow back.
