I like the selection, but as an artist, cenezoacraft makes me so SAD. the textures, models, and animations show talent, but that talent is utilized in what I feel is the wrong way. I can't tell what's going on in the textures, and some of the mobs look so strange with the tiny eyes and in some places detailed, in some places simple models
I watch videos like this quite often, I would even call it my wierd hobby. You're right and it's quite a common problem. Often the mod author knows how to do one thing, but to create a quality mod you need to be able to code, and model, and draw on models, which is actually much harder than on a flat canvas (im somewhat an artist too).
