Heya,
Overall good images.
Criticism: the images are all dark, some under-exposed almost (not quite, but almost), and very flat. Not a lot of pop. That's ok, if there's a lot of contrast to break up the flatness. But with low contrast, you need color to provide that separation. So I would add that to the post processing. Increase contrast, or increase some saturation, or both. I would definitely apply some Levels to get the light right too.
Here's some edits of two of your photos:
All I did was added masks. 1) Levels. 2) Brightness/Contrast 3) Hue/Saturation. Took about 1 minute to do it, without even using presets.
Very best,
