And by the way, i want to learn how to make decent textures but i dont really know how to, i want to be able to make decent textures that aren’t like realistic, but are decent like the one below.
I would say smoothen some faces to make it look less blocky and more bushy.
as for a texture try to take some pictures of real life pine trees. you can wrap them on meshes or anything else in studio using the materials manager. the overall shape is pretty good.
Try use a greater variation of sizing, shape and rotation for the leaves on the tree. As for the texturing, that just involves finding something that suits the style you want to go for.
