Newcomer's "Horror" Photo Manipulation

[Marin]

Hello!

First of, let me tell you I am very happy I finally found a quality forum of this kind! Hello to everyone!

First, to introduce myself - I am an amateur digital artist/manipulator, creating mainly "dark" and "horror" pictures, usually out of everyday photographs, retouching them first to increase overall quality.
I attached here my latest work, since I am very interested in your comments and critique because I am aware I am an amateur and my work is low quality, but I tend and would like to improve, and what's better way to do that than have your work rated by professionals?

Thanks in advance on your critiques!
