You've made a log cabin, so you're doing pretty good - I've never made one but it's on my list. You might want to try a Bento Box (my avatar). It also uses strips of fabric but you can change up the colors to match within each large block or oppose each other. When I made my first one I'd get up at 2am to run to my design wall and move a few of the smaller blocks around and then do it all again the next morning. You can make it with planned fabrics or as a scrappy.
