I'd also just echo the other members thoughts on phrasing. Try and anticipate each approaching phrase, work out in your head what you want to hear and then try and play it.
Frank Sinatra was a master at phrasing, anyone can learn a lot from his tunes. For the same line or phrase in a song sometimes he would add in extra words or sometimes take words away, sometimes he would sing it with a triplet feel, sometimes he'll emphasise different words, other times he'll hold on to one note a bit longer than before.
Kirk also is very good at phrasing, check out some of his tunes on the
radio and listen out for similar things.
