Don't you find that the crop is too tight here? A bit more negative space would result in a more compelling image; here the rock looks quite crowded in with this framing.
As for the black background, it can be effective, but I suspect this might have worked better with a lighter background. This would look really interesting against a white background.
Did you light this with a camera-mounted flash? The light looks like it is straight on. That's not ideal, I think. A plain background often works best when it contrasts sharply with the subject, but in this image, the rock just fades into the background in some places. Sometimes other kinds of lighting work better--for example, lighting diffused by being bounced off an umbrella or aimed from the side.
I like the colors texture of the rock; but as have been already pointed out, cropp is very tight; also won't a uniform lighting might work better?
Perhaps somewhat. One reason I use continuous lighting rather than flash for things like this is that I have a hard time predicting what various lighting placements will do. With continuous lighting, I can move the lights around and see what it looks like.wouldn';t a uniform lighting cut down on the shadows and textures?
I confront this mostly in shooting flowers. Most often, I use one bounced light for general illumination and a second direct light (also diffused but not bounced) to generate shadows and depth. Here is an iPhone shot of a setup I posted here years ago:
Here's an image shot that way. It's an Ito peony, but I think not the one in the shot above because the direct lighting isn't coming from that side. You can see how the side lighting creates shadows;
One nice thing about the lighting I use is that it is cheap. I bought two very inexpensive "hair lights", which portrait photographers use to get illumination from above the subject. One of them (a B&H store brand) has a socket for holding umbrellas. For diffusing material, I tried all sorts of materials designed for photography, but in the end, I settled on sheets of parchment paper my wife had lying around for baking. The lights are halogen floods that you can buy in any hardware store. They are fairly warm (3000 degrees kelvin), but I shoot one image with a whiBal card and then use that to adjust the white balance of all the rest of them.
Here's an image that shows what I mean about a crisp border between subject and background.
Apologies to folks who have been here a long time and have seen these images before.
+1 to Dan's comments
I have done a bit of tabletop work and as I use studio lights, which have built in modelling lights, it gives me much of the same benefits as using fixed lighting, but I have more control as I can easily vary the intensity of the lights as well as the light quality (and direction), depending on the light modifiers I happen to use.
As a general rule, I use at least two light sources; a key light and a fill light. My fill light is often just a piece of white foam core that acts as a reflector that reflects the light from the key light. I will sometimes get a bit fancier, like in Dan's shot and will use a second (or more) active light.
I'm no fool so here is my new and improved version. As suggested I used three light sources, changed the crop, put some colour into the bg, and pretty much changed everything. The top of the dark rock looks very dark perhaps because it was still wet. This is a 14 shot stack but even so I missed the extreme back of the rock focus.
PS it looks a lot better in the Lightbox
Brian, do you have the book Light Science & Magic? It is really very good. by the way the last image looks good.

You should Brian! Rather than working in a linear manner from start to finish I'd suggest selecting a chapter that aligns with what you shoot (or are shooting at the time) and follow it in detail. In this case you could do worse than start with chapters 4 and 5 of the 5th edition ("Surface appearance" and "Revealing shape and contour").
i really like your new version
