I’m guessing the sharpening was to bring out the texture of the skin for a harder look. You can get the look with duplicate layers and changing the blend mode. The super heavy vignette detracts from the image because you are darkening the forehead and the focal point of the image is now her nose.
This isn’t sharp, it should go in the bin
This isn’t very sharp, the noise is bad and his hair blends seamlessly in to the background making it look like he is a face floating

This one you could have used the negative space a bit better. As it stands now the girl is looking out of the picture. I would have preferred to have framed her on the other side of the photo so she was looking in to the photo instead. Some context could work as well, what is it that she is so focussed on outside the frame? The horizon is tilted as well
Here you’ve brought the over exposed outside back into the picture but it doesn’t look very good. The colour fringing you get from doing it isn’t worth it. Again a tilted photo. This one you could have made better by not including the outside. You have the great side light from the big windows going so a darker background would have helped bring your subject out more.
Not sure what you have done to the background here but it doesn’t look great with all the blotchiness. I would have preferred her to be on the other side of the middle looking that way
This photo would have benefited from a longer focal range and a deeper depth of field. Her eye is sharp as is his ear but his eyes aren’t
Here he is in focus but she isn’t. For these something like an 85mm lens would have been ideal. The background would have been blurred yet you could have had a deeper depth of field. With a short lens like a 35mm you will struggle to get both.
Not sharp, stick in bin
I like this shot, the leading lines work well and the colours complement. Advice would be to tell the people to walk really slowly towards you. Basically in slow motion. It makes getting focus easier but also prevents the motion blur you have on their feet. It isn’t a dynamic enough photo to really make use of the motion in it.

Another one I like where the hair works with the background. Was it intentional or did it just happen to be so?

This I could easily see in a clothes store on one of the walls
I think you are doing well. The photos aren’t perfect and you are limited by your gear but you’ve done well no matter. The portraits have good expressions, the colours are mostly there (some difference between various shots in the same album but no massive difference ) and you’ve made your subjects look good. My advice would be to cull the shots you have though, if they aren’t sharp and crisp get rid of them. At some point you need to expand your lens collection beyond the 35 1.8 which will make things a lot easier for you. You make good use of the natural light but you are at a stage where you ought to be learning how to augment it be it with reflectors or a bit of flash. Portraits with catch lights look a lot more alive that without.
