Nice, but to note that Instagram only has individual styles to choose from, so there is barely effort apart from taking the picture. Samsung is a phone that has cute camera accessories, so images aren't hard to take either.
Usually I'd say that the image usually depends on the background, and what you have on the camera's point of view is honestly really nice, you've set good angles where the picture can be taken from. When you get better you should use a actual Camera, and try to keep the photo clean, meaning without having it edited, this style that Instagram applies onto your photo makes it more comfortable to look at. If you want to try, keep it clean in the future, real skill comes from that. I personally take a lot of photography myself, and to respect your ways of taking photos you should do what you want to make your pictures look good.
