the 1st recording is a riff my friend and i just made while drinking. we were going for a mix between classic rock/blues with alternative/punk, just something we dont usually here.. we're still intoxicated so we dont know whether to keep it or not..what do you think?

the 2nd recording is an acoustic pop song that im doing..it starts slow since theres no vocals or keys in the beginning, i dont have the piano track on it yet. but the beat drops in eventually and my guitar solo is at 2:10, does it fit the song?

It works, but stuff like this can't really be judged unless its part of a whole song. Usually more a song construction thing rather than a "the master riff" issue
