I gotta say, this is a really attractive tileset! It's got a nice solid, smooth look to it, and gives an overall great first impression. I hope you don't mind if I nitpick and gush at the same time, I'll try to keep it short. Also keep in mind I'm not sure how much of this is pure Baskerville font, and how much has been edited or created by you. Mostly it's about your aesthetic choices rather than pixel-art skill anyways.
To start with, I like what you did with the heart, diamond, club, and spade. It gives them a nice "old deck of cards" feel, which I think goes well with your font choice. The ☼ is also really nice. Your lines have a good balance of tapered and untapered (looking at the <, >, ^, and numbers mostly) and I like the log tile a LOT.
I think your asterisk is too different from the ☼ though - powered mechanisms alternate between the two. Actually, the asterisk just feels out of place in general. The infinity sign could use some smoothing, and, to be super nitpicky, the small 't' would look better one pixel to the left. It's technically centered where it is, but because the crossbar and the curve at the bottom are both more to the right, it looks lopsided (i warned you i was nitpicky, im sorry). I'm curious why you inverted the division symbol? Also I think personally I would also change the trunks of "cap" type trees to the pillar tile (in your last screenshot they show up as O's). I really like the inversion of the cent symbol tile, it makes the hatch covers look great. Your walls, ESPECIALLY your rough walls, are very attractive as well. The patterns in the rough walls remind me of the old ms-dos games i grew up on, and gives them more visual interest without being distracting.
Overall, it's a really good looking tileset and I will probably end up playtesting it even though 16x16 is too big for me. I think my favourite parts of this are the card suits, font choice, and rough walls. Most of my nitpicking is fairly insignificant, I just know they would bug me while playing. I think it's a 9/10 for me? Great work, and thank you for sharing it! ...Sorry for the textdump :'D
