It would be good to see up-close shots of plant features. Use the macro-setting on your camera.
Of course, you may need to wait until June for the flowers to return.
Photograph the front of the flower, particularly a macro shot of the center with stamens and styles.
Photograph the back of the flower including details of the sepals and hypanthium.
Photograph ripe rose hips as well in the late Summer or Fall.
Photgraph the leaves including the leaf base and stipules. Also count multiple leaves to determine the average number of leaflets. From the pictures, it might be five leaflets.
Also photograph young stems to determine the amount of prickles and hairs.
I will add that the general look of your rose reminds me of the Smooth Rose (Rosa blanda) native to eastern North America, but additional information and comparisons must be obtained to determine if that is accurate.
