No apologies necessary. I work in grams as well, when it comes to soapmaking.
I agree that it seems like a lot of water. Your water to lye ratio is very high at 2.78:1 or a 26.5 Lye Concentration. I tend to prefer something along the lines of 33% to 35% for new-to-me recipes (or a 2:1 water to lye ratio.) Not that I didn't use the default settings for the calculator of choice at the time when I was new; I did. More water in the soap when making it, means the soap takes longer to loose the water. It mirgrates to the surface and evaporates eventually, but high water soaps are also more prone to soda ash (a chemical interaction that occurs and looks like a whitish ash that forms on the outer surfaces of soap sometimes.) Soda ash is nothing to worry about in terms of safety - it is not harmful and it washes off, but some folks don't like the look, plus it mutes your surface colors of the soap. Also, I and some others have found that soap with activated charcoal seem to be more prone (or at least appear to be more prone) to soda ash formation. Maybe it's just because whitish powder on the black surface is just more noticeable than on, say a white soap. But it is only cosmetic (aesthetic) and not harmful and doe wash off.
Back to the fragrance. Depending on the specific fragrance, 4.5% isn't usually a problem as long as it is skin safe at that percentage, but some are not. So make sure you check for each fragrance you use in soap. And I've found some fragrances more likely to leak out like that than others, even when used at safe amounts. For me, I think it's mostly the spicy ones I've used that seep out, but there are probably others that might do that as well. Only once did it not all re-absorb, however.
Incidentally, your soap design is very nice looking. The half moon embed in the dark sky appeals to me.
. Good luck
