That didn't turn out too bad :)
UV unwrapping can be a bit of a pain in the system, it's one of those things you just have to keep doing. The boxy shape that you have there would have actually been pretty easy to learn off, all you're doing is making seams which are like little cuts so that your model flattens out nicely.
Then into a painting program you go and paint your texture. I think some of them can connect to Blender so you can see what's going on live but it's been a long time since I worked like that, I just bought BPainter because it was easier.
Did you mess around with the scale of the procedural texture? Sometimes you have to make it surprisingly large or small to get the shape/pattern you want. Still not bad though :)
I've been practicing a bit with Krita to do the textures, but I'm further behind on that program.😨
In terms of knowledge of handling in terms of procedural texture, this time I did not mess with the scale as much as I did on other occasions because in some cases, especially when combining noise nodes with voronoi texture, I noticed that in some occasion ended up nullifying the effects he had achieved when he manipulated the scale.🤔
So this time I just touch the rotation a bit using the keyboard shortcut: ctl T from node wrangler which generates a set of nodes that allows me to manipulate the scale, rotation and location of the texture map😗
I must continue learning much more But nothing in the learning process is instantaneous, so I must practice and look for material that teaches me and helps me improve.👩🎓
Yes often combining nodes for procedurals is a lot of fiddling around. You have the right attitude :)
