Several comments, with the first one "negative"... You looked seriously better your first shave than I did! A little humiliating for you to do as well your first shave as I did after about one month.

I noticed a few times you were indecisive with the blade angle, before settling on the hold and angle of attack. These times were infrequent, and I think you selected the right angle each time.

Seriously, nice work!

You wondered aloud midway thru whether your growth might have been a little too much for the straight razor. The answer is no. There is no such thing as too long for a straight razor.

If your whiskers are long, but not too tough, you can simply shave them off at skin level as you would expect to. However, if longer, there are several strategies you can use. The initial goal is not so much to shave as to reduce the length of your whiskers close to skin level, after which you will shave in a more conventional way. To reduce your whiskers, you might try laying the blade flat. Your whiskers will be pushed over by the blade before the blade bites into the whiskers to cut. So, you will be cutting off whiskers at a diagonal angle, which means you have to cut thru more whiskers. There will be some resistance to the blade, (as there is with any commercial blade when shaving similarly long whiskers), as you cut off the tops. Because your blade is flat, you aren't likely to experience razor burn. In fact, if done right, the edge might not, and probably won't even be in contact with your skin, being slightly above skin level.

After a WTG pass or two - and I don't relather after the first WTG pass... up to you - I relather and shave WTG in about the way you shaved on your video.

Your first WTG pass doesn't have to use the flat on face approach. But, if the whiskers are tough and long, it might be a useful approach.

Your use of the DE was obvious in your techniques like stretching. You were ahead of the game, obviously.

I enjoyed your video, (and my wife enjoyed your jerky flavors. More later on that.)
