is it worth it? 18-45mm lens vs 15-30mm lens

[DanielsanThe3rd]

hi i want to hear the opinion of actual photographers cause i'm still kinda new at this. i have a EOS R100 with a standard 18-45mm kit lense (RF-S18-45mm F4.5-6.3 IS STM), and have taken some nice/great pictures of landscapes and other stuff if i do say so myself. I just went and bought a new lense a 15-30mm lense (RF15-30mm F4.5-6.3 IS STM) i bought it because i wanted a wide angle lense, but when i tested it at home and in my local park, i realized it wasn’t as wide as i had expected it to be, especially when comparing to what i already had, and the price. it cost me around 700$ maybe a little less (im converting from danish kroner), plus i have other things i have considered buying. im considering returning it and getting the money back, but i'd like to get opinions from other people who do this more than me. this monday my school has a studio trip where we go to prague for a week which is why i bought the lense today. the first set of photos are with the old lense i have, and the second set is with the new one.

The funny thing is I also found this website after writing here the problem was just that it was closed this weekend so I couldn’t get the lens before going of to my school today, and then of to Prague. But I might get it when I get back, if I can sell my new lens, cause apparently the shop I bought it from has a no refund policy even they never actually said that to me, so il have to sell it at a lower price then when I bought it 😞
