Here's the thing--I really feel the number one MOST IMPORTANT part of getting a good shave here is LATHER. Once you figure out how to get a good lather, then you will be well along the path to good shaves. Hell, you can get a good shave with a bic disposable, once you figure out lather.
Your soap is good, by all accounts--I've never tried it, but plenty of people have and they like it.
Forget the glycerin. You're adding it because you keep seeing people talk about it on the forums, but let me ask you this: If glycerin is necessary for getting good lather, then why don't any soap makers send little bottles of glycerin out with their soap? (I'll go ahead and give you the answer--It's because they have worked their butts off to make a good soap that should lather just right with a little water, a nice brush, and some skill. If glycerin needs to be added, then the soap has NOT been made right, and it should be relegated to the shower).
I assume you're using a brush, you haven't said which one but it's not that big an issue. Unless it's falling apart on you, it'll do the job for now.
You've got soap. You've got a brush. Now you just need the skill.
Have you watched Mantic's videos? I hope so. If not, do that. Watch them over and over. See how he adds a little water sometimes? See how he checks the consistency? It should be smooth and slick, with no visible bubbles and a slight sheen. You should be able to rub it between your fingers and not feel the prints on the fingers touching each other. THAT is the key--the lather forms a slick cushion, not a thick sticky paste, not a grippy film.
Put that on your damp face, work it with the brush a bit to get the whiskers lifted and make sure they're well coated with lather, and wait a minute. Let the lather be your prep (a hot shower before doesn't hurt, but if you want to avoid it's ok). Wash that lather off, then relather. Strop, and try shaving. You razor should glide smoothly, without any drag from the lather--drag means you need a touch more water.
Your skin should still be slightly damp and a little slick after the blade passes over. If it isn't, you might need to work on your water ratio a bit--if it's too much water, then it won't be slick, it'll be slightly "grippy". Too thick, and it'll leave a sticky layer.. But the number one thing is the shave, and the feeling of the blade over your skin.
Trust your face. If it says "Too dry", then it probably is.
I hope this helps!
