Very nice. Looks good on you. Hope you enjoy the new look.
Concerning concerns with razor shaving, consider these points.
When starting out, take it easy. Shave WITH the grain. Don't press too hard. Don't aim for a super smooth feel just yet.
After a week or so of daily shaving, if no irritation issues arise, again, start out shaving WTG but follow up with Against the Grain. Again, don't scrape your head sore, just pass over in the other direction. Give that a week of daily shaving.
Gradually increase the pressure of the razor for the closeness of shave desired and to avoid razor burn.
Do follow up your shaves with after treatment. Witchhazel, a head lube (like from Nivea or Head Blade). It's like a hand cream for your head. After shave (recommend Pinaud Clubman). Some use bump patrol and could comment on how that helps.
Thanks for posting the pictures.
