If you want feedback, perhaps the “focused critique” subforum is a better place.
Colors, textures, and materials are all solid. Composition is initially strong, very good focus, tentacles are the same color as the background, so they sneak up on you. Geometry and modeling looks mostly solid.
However, the composition is very flat. There is almost no secondary interest, and no depth to the background. The foreground is the car, which works well to give a sense of separation, motion, and danger. The middle ground holds your focal figure (the tentacle girl) and a few other elements. But the background is just a wall, with a bit of ivy growing on it.
The modeling of the curb is odd. Old broken curbs are many pieces, or made from brick or stones, and curbs in one piece are built straight. There would be no way for a curb to get to how you have portrayed it, unless the person who did the concrete work was just really terrible?
To improve it, I recommend adding an arched gate in the wall, with a secondary focal element in the deep background. Haunted house is a classic, but it could be anything. You could also pervert some of the middle-ground elements, to show that it’s not just the girl who is off.
