this looks like a snapshot. usually when people on this forum click on a thread and come upon snapshot-like photos, they just leave and not say anything
I am just a hobbyist so I am not speaking from any great experience or knowledge myself but, you cut the dogs paws off and I think he is too centred. IMO the B/W conversion doesn't work because there is not much contrast so the dog is the same colour as the background. You have caught a lovely expression on your dog's face and I wonder what the colour version is like? Perhaps try cropping your photo in portrait so it is a head and body shot. I would also experiment by cropping away the space at one side (either side) so the dog is not so centred just to see what difference a less off-centre composition might have made. Hope this helps :thumbup:
Be kind to your viewers. When you center your subject like that you leave them nowhere else to look and they move on quickly. Leaving space in front of your subject suggests motion and anticipation where as leaving more space behind reflects an ending or passing of the moment. A good photo needs movement either way.
Be kind to your subject. Don't cut off limbs or make them seem stiff. Either capture the whole subject or a whole segment of it. Catch them in a pose where either they are or at least appear to be about to be moving gracefully. Again, motion is your friend.
All in all it's a good start. You have a great place to shoot and a fine companion for a subject. Keep working on it.
