Well, your kitties are adorable as you already know
As for the photos, I think you did quite well.
The cropping in the tower picture is interesting, and not something you see very often. I do wonder if it would slightly more effective if it was just a little bit wider so you had just a bit more perspective on the environment; maybe if you include part of whatever has their attention. Without the rest of the photo though I couldn't say for sure, it entirely possible that this is the best possible cropping.
You've got nice perspective for the second one. I feel like I need to reach right out to it and rub some belly fur! I think that you might want think about depth of field a little bit more when taking shots like this. I feel like it might have been even more effective if his face was nice and crisp, but you had a really short field making his back legs start to blur. Of course I don't know what kind of camera you're using so I don't know if that's even possible for you, but still...
The third photo is my favorite. I think your depth of field is perfect; it would detract from the whole thing if you had anything in focus in the background. Your cropping is very effective... My attention goes directly to those big bright eyes. If I were going to suggest anything, it would be to try and dodge a little around the eyes and base of the whiskers to see if there's any fur definition that could be brought out.
Good job on your photos. It's sometimes hard to get interesting photos of pets, because everyone does it, so most people have seen it all before. But I'd say you're off to a really good start with some really nice photos!
Wow! Thanks. I really
appreciate your comments.
