2 things: what's your honest opinion on my style and are these textured paintings or sculptural reliefs?

I have been working on this style of are for about 2ish years and I would really appreciate some thoughtful opinions from artists or art enthusiasts. I would also like help classifying where my art would fit, is it a painting or sculpture? I'm hoping to be able to submit to art show; maybe, even apply to grad school; but am unsure where to categorize my pieces. Any help would be appreciated.

The style is really abstract. I created each piece by building up the layers over time. The process is very much additive and I feel like I'm sculpting with paint as I work. I'm deliberate and thoughtful with my placement so it's not random but they are unplanned free-formed, and improvised.
