welcome. Decent shots for someone who is beginning to explore the world of photography. Here's a couple of observations:
#1 is technically ok but is not very interesting
#3 there is a very tiny area that is in focus and that's kind of distracting. Also, you should have taken a minute to clean under the strings a bit. The dusty pickup and bridge are distracting.
But, as I said.. a good start for someone who's just starting !
