Adding some variety to my beats

just wanted to get some tips from you guys on mixing up your beats. I'm feeling good about getting down my main beat and groove, but I want to step up my game as far as adding some variety to them. I don't want to get them too complicated, though....I'd rather have a good strong beat than a muddled up complicated one. I make my beats to rhyme over. So any tips would be appreciated.

thanx, Season

when I try to switch my beats up, I listen to different genres of music
for a minute.
