Try jamming along with your favourite songs, or with songs on the radio. Try to reproduce the style of playing in the song. This exercise will make you a more versatile player.
Recording yourself can also improve your playing. If you listen to yourself, you'll discover shortcomings in your playing and you can work on them.
Get hold of a multitrack recorder if you can (borrow or buy one), and record a chord progression of your own. Jam along with it and you'll see how much better you play when you set your own groove. Be bold and try to fit in every technique you can. Play both fast and slow parts.
