Not bad for a start, but there are thousands of mods, are you more interested in maps or just skins for weapons and characters? You can try GunGame mods, here you get a gun at first, and with each kill you get a new weapon, but of course, first download CS 1.6 with bots, I downloaded it here
https://all-cs.ru/cs16/sborki/cs16-s-botami.html . Or download a Deathrun map, here you can play with a bot in one team, I especially like deathrun_qn_wild_b1 and deathrun_orange. When you learn how to play with bots, let me know, maybe you'll want to play online later?
