Unable to help with you lack of models, however, you have opened up quite a lot of things that you can try now...... It's up to your imagination really.
However, even a cheap diffuser will help you out on a lot of subjects, partcularly human shots etc. If you want to do things the old fashioned way, you could always buy some Different coloured Gells to try, however, the digital age has taken over from that sort of thing, just worth learning to do it for the fun of it really.
But certainly, get yourself a nice "COLLAPSABLE" light box & diffuser or umbrella, they all do different things and the upside of the digital age is that it now costs next to nothing to experiment.
Using a light outside can be very effective sometimes, especially if you are into shooting bugs like spiders and things.......
Just a thought......
