So Frank mentioned getting a tile set mod that replaced everything with images, I second this but just for getting one that replaces all the tiles with prettier characters - it's been so long since I played the game that I can't remember where exactly I got mine or even have the "file" (actually just a PNG with all the different tiles in it) to send you but I think I got it from an old kruggsmash video (I just can't remember which)

Edit: also, this video is good and how I learnt the first bits about how to play the game (though it's a few years old now, so idk how well it still holds up in terms of stuff like the UI and stuff, though I think all the base mechanics are still the same)
(Also the video includes a link to an improved tileset and colour scheme than the base game comes with, though it's not the one I used to use which I can't find rn unfortunately (also also the YouTube channel the vid was made by is great and really worth watching))

Edit 2: also I wouldn't advise getting any mods until you're more used to the game as a whole, bcs its very easy to accidentally fuck up your dwarf fortress install by adding mods incorrectly and the base game is complicated enough to understand as it is anyway
