put references inbetween layers, to use in the middle of drawing, but don't post pictures with references themselves unless you have a good reason for it.
Using references is how you build your 3D kinesthetics, and if you have that, you can eventually even make art completely from imagination.
I would also advise to you, to paint a bit instead of just sketching, since that will teach you proper form, so then your drawing will come out more well built.
