First off, the marble background, if that’s what you were going for, is phenomenal, the color and texture is spot on.
Your colors are begging for more saturation, rich beautiful saturated colors. With some work on perspective and some shadows to support it the realistic vibe I think you’re going for would really work well. Unless that’s not what you’re going for and you’ve got a vibe and style you want.
I can see some good wet on wet (like the rust suggestion on the pipe, among others) which I love, and given your couple of months introduction is just great to see, wet on wet has a ton of depth to it. Keep experimenting with it. I can see you playing with shadows, they are so hard, but keep trying. Shadows can do so much heavy lifting in a painting when they are done right. 💛
