Check out these little snippets of comping based on a Brazilian feel. I basically took the guitar and bass parts and put them together. I added seconds to the bass line to add a percussive sound to the rhythm. The guitar more so than the piano plays a very rhythmic part in this music. Also that fact that I grew up playing guitar, I was drawn to this instrument. Listen to real Brazilian music and check out the guitar. You'll hear these rhythms. Try and recreate them with the feel that you hear.
Check this out. It's the 'A' section from 'Girl From Ipanema'. All off beats. I know a great jazz guitarist that struggled with this rhythm. It takes a while to get used to it. Try playing it and counting the 1 and 3 of each measure out loud.
