I've made a sort of dark wizard tower/barrack's and i wanna know if i should continue to test this or just keep to my regular stuff.
A bit dark in color with little contrast, I would edit that. otherwise there isn't much detailing on it. Looks like a pretty quick little project. My advice is to spend a fair amount of time and effort on it then update this, because I do like the theme and I think you could keep going with it.
Looks nice but needs work, reminds me of my first time doing a netherbrick tower (mine was bigger and made in survival though, was made to be a storage room) But if you keep working on it, and perhaps look up some concept art of something similar. Who knows, might come out as something you enjoy :D
