I am really not a photographer, but I am an artist, so I appreciate photos that have a good composition, good lighting and either color or black and white that uses great value spread (light grey to dark black) Take some more , lots and pick out the 10% that are good. And gettting your new Nikon will be so much fun!
I bought my hubby one for Christmas and he has a lot of funwith it.
Don't be discouraged, but dn't falsely think these are great. They are a humble start, but that's GOOD!
