Great Job on Latin Time. It is an easy piece to play, to be sure. But a song doesn't have to be complex to be interesting. The rhythms, the two parts in harmony, and spaces in this tune always make it a fun and interesting song to play in a group.
And the 12 bar blues is always fun, too. I encourage you to play this progression with a song like Hound Dog, and try for a bluesy sound and then do it again but try for a Rock 'n Roll sound. You can do this by altering your strum a bit (emphasis) or by tempo, or with your own unique style of singing.
