Model's aren't overdone. They are still a basic subject that every photographer
should learn to photograph.
If you are serious about photography and want to be professional, then try learning
photography compositions (rule of thirds, leading lines, natural framing, etc) as a
basic structure. This can work with any camera.
For more professional cameras (e.g. Canon DSLR, any camera that has a manual,
shutter, and aperture priority setting), try playing around with depth of field. This
is basically a focus setting that allows you to either focus on one subject (with the
background not in focus) or all of the photo (subject and background). Your photos
are currently in a sharp depth of field and I would like to see more shallow.

And if you are wondering, I am a photographer myself, and a student still learning.
