"However I am in my 5th year in college with (graduating this year) and have been trained traditionally. I have never taken a digital art class or even a graphics class"
That's what I thought after seeing your drawings. You have the general technical skills obviously, but it looks like your handling of the digital tool is still lacking.
The first four piece from left to right have rather blurry and messy colors. It seems to me that you overused the blur tool and made every shadow/edge super soft. If you're really using the blur tool, ditch it. Try using the smudge tool where the colors are supposed to be blended.
Take a step away from the complicated artworks and just do some still life fruit paintings for now. When you feel that you've got a grasp of Photoshop, then move on.
I'm in my 4th year in college, and I want to study digital art as well. Unfortunately, the school I go to doesn't offer many digital classes, so I'm doing an art degree. So I'm no expert in digital art, but from what I've seen, I can give you my best advice.
Your "Eyes Don't Hide" is captivating and emotional, but I would make the colors and lines more crisp. You did that with the tear in the right eye, and if you want to make the eyes pop more, you could add more detail in those as well.
"prison of my own devising" has great contrast with the colors in the skull and the wall surrounding it. It looks like a traditional painting, so you did a good job imitating water based paint dripping!
