I like it man, just a couple tiny suggestions. Instead of using gray wool use cyan stained clay (it looks gray), it looks like rock so it'll fit in better with the stone and cobble c: Maybe add some leaves or something to add a little bit more color to the cave, or if you don't like leaves then maybe add some ores like iron or coal to add a bit more color as well. Other than that I really like it, whatever it is I can't wait to see more. Keep it up (:
I think the amount of gray wool you have is good, just replace it with the clay and I think it'd look good. If you're using worldedit a balance I use for my texturing of stone is normally 65%stone,20%stone:5,10%cobble,5%159:9. stone:5 is just Andesite and 159:9 is the cyan clay. Ofc do whatever you think looks best, I think what you're doing looks good already (:
oooo I like it. Also if you want to use vines but don't want them to grow just put string right at the height that you don't want them to grow past and it'll stop the vines from growing and nobody will notice the floating string (: Is that the tall grass and sunflower stems that you used? I don't think I've ever seen that before, I like it. Overall the green adds a lot of color and life to the build, I can't wait to see more.
Yeah, I used the tall grass and sunflower stems. I thought it would be a good alternative to vines since these aren't climbable.
I like the build, but most of the time builds look a lot better as rustic. Like making the rail track a bit torn down or something, and maybe add a few stalagmites to the roof to make it more like a lowly edited cave. And to make it look more like a realistic cave in general.
