you have many images that are just snap shots. like this dog is just sitting here doing nothing. you have no description. you mentioned super dog, but there is no explanation why.
images don't only have to look nice, but look nice in a house
i like this shot, but only the buildings. the foreground is dark, has that sign, it doesn't catch the eye, but the skyline does. you have very few keywords that would attract attention.
you don't want any effects - they don't help. unless this dog ate plutonium, effects like these may scare off buyers, because they can do the same in their phone. the question is here - do you have this hanging in your own house? and if so where? is it framed? presentation is very important, getting down on it's level, getting eye contact, no collars, better backgrounds - you want something a buyer can't make themselves.
overall the dog shots are snapshots that would only interest the dog owner - you. the rest has a feeling of vacation travel, but it doesn't really catch the eye. you have to have descriptions and better keywords. you need more images, and to start people in galleries. you have to do your own advertising, but you also need more work. you also want a biography. i would also change the avatar, your head is lost in the background, and the trapezoid shape suggests it was crooked and you left the crop. go for color.
