Work with the camera you have now, then worry about better/more expensive equipment. I knew a lady that made some decent money on the side by selling her photos, and she used an iPhone 6. (Which, compared to the phones today, has a "terrible" camera)I think if I am going to learn by doing I will need to learn to operate a better camera. These are gorgeous!
Work on the angle at which you take the photo, lighting, spacing, etc. IMHO, angle is everything.
