Love the pets! They're all so cute. My favorite of your photos would be the one of your cat. I think it's a great picture but the background is a little distracting (this coming from another amateur haha). The photo of your dog is also nice and I think the puppy is adorable, but the photo could be a little less fuzzy. And don't worry, sometimes I over edit my photos a bit much too.
I pretty much just take photos of my pets and fish. I like to go out and get landscape/nature photos occasionally too, but I am pretty much a noob when it comes to cameras. I have a nice camera that I got for Christmas (because my family noticed I was always snapping pictures). I know how to use the macro setting and change the exposure which was about the only thing I learned how to do in my photography class. It was really more of a photoshop class which doesn't help me, considering I don't have photoshop.
This is one of my more recent photos of one of my crowntail bettas. I haven't touched it with any sort of editing besides cropping out the reflection from my tank lights on the water because it was distracting. What do you think?
