I think it is great that you are developing a style. I think the title of your post states your intention quite clearly "illustration". I also think that you did a great job at it. I enjoy a lot of the commercial images that were created in the 50's as it was the start of this type of artwork. Not every photo can be turned into a successful illustration. You need a keen eye to see the potential and end result of each and every shot. I would say that you have the eye. I find that most photographers are recorders. They see, they capture, the reproduce. Others are explorers, they explore and find new ways to look at something or say something. The last group are artists, they bring something to the table that would never exist otherwise, imagination with just enough reality to keep it from floating away. I think you would fall somewhere between the last two classifications (great place to be).
Keep up the good work, and post often. I will be keeping a keen eye out for you work.
