OK, Wayne, so you have this water droplet giving these colors. I'd work with this one topic and see if you can master the technic of getting the shot. Then look to see how lighting the drop or making other changes might improve it.
As I always say. Print it out in B&W and look at the form. Draw on it, and see if this is as you can best imagine it to be. Does this excite you? If not, find our what might do that.
In the end, this picture has to be something you know is what you are proud of. At this stage, you have wet your toe in the water of the project.
There is so much you can do, but what you happen to get as you start, is unlikely to be your very best. if you just move to something else, then you might miss a great opportunity. The idea is to find what interests you and have you imagination exploit it to the nth. You now have to get that somehow into the photograph.
Will it be like the picture you have? Perhaps but I think it will show its inheritence if you do the work.
