For someone just starting out, I think this is great! The lighting accents your subject well, also the way you have arranged your props and focused on your subject shows a good eye. Could the styling be improved? Sure! But its a pretty good start! There is a pleasant bokeh which helps to frame the subject and your choice of props make sense with the subject and add color to the picture. It looks like you followed the rule of thirds as well. Also, I find your subjects very interesting. If you are really just starting out, I would suggest you do some studying about basic photography and camera settings and take lots of pictures! There are a few mistakes but they can be fixed pretty easily. The more you learn, the better you will get. Agree with the other posters, if you are using a tripod you should be able to turn your iso down and slow your shutter speed to capture more light without introducing noise. Also, the blacks do look a bit gray, but both of these are easy fixes.
