>>4423852 (OP)Effort postin. This is at the level I'd expect of a high school or very intro/101 college class. You should be further along if photography is a special interest. While the subjects, genres, and styles can vary, a portfolio should be cohesive enough to at least appear from the same photographer. Also consider that most all of the images are 3:2, but you have one near 1:1 and one near 2:1, either increase the aspect variance overall or make it more cohesive.
On the technical level, there is definitely room for improvement, even with these small samples. Your editing is a bit heavy on underexposure / contrast / "crunchiness", consider making use of the histogram for a more palatable contrast level. The strong vignettes on E and P look awful. Good editing just comes with time and practice, so I mostly want to focus on the composition.
Go over your photos in Photoshop and play around with different crops and framing, use guidelines to help. A big part of what elevates a good photo to a great one is all the minor details. Consider this slight adjustment I made. In your photo, the horizon is near the middle, but the bottom half feels so much "heavier" than the top half. By shifting the horizon down a bit, it looks a bit more balanced. This also brings the buildings more to the forefront as the subject, and hides the empty space on the bottom. It also feels a bit more balanced when looking at it left/right. It also leaves a bit of "breathing room" at the top of the big building, something most of your photos lack.
