Very nice start. May I suggest that you use a lower shutter speed to get some movement in the pictures. Your compositions are great and the F-number makes it very real. 1/60-1/125 and panning mode 2 and 3 works great. Sorry if you already know this, but I feel that it's a good advice to new photographers.
I'm looking forward to what you bring next.
Some really nice first shots for your gallery. I especially enjoy the 3rd. Listen to what fishy said and work with some focusing and exposure as well. You can really make things pop if you get everything just right. Good luck I hope to be seeing more shots from you.
