Newby modder needs help

Hi, I've been trying to mod my game a bit and just learned how to do that (about 2 days ago) and I can't get the results I'm expecting. I got a lot of graphics and visual mods, yet the game still looks pretty 2010. The lighting inside is really good, but the outside is bleak and ugly. Is there something I'm doing wrong?
