I’m sorry but I don’t really see the need to showcase this, all I see are four blocky parts with two of them being textured. I’m well aware that it’s supposed to look simple but there doesn’t seem to be any effort put into this.
Correct me if I’m wrong, but all I’m seeing are four rectangular prisms that are slightly scaled larger than the blocky-type arms, alongside them simply using studio-colours/materials. This doesn’t exactly showcase much genuine thought into design or craftsmanship of a concept.
Perhaps look online at how to simulate t-shirt sleeves and bandages in 3D softwares, such as Blender or Autodesk Maya.
Autodesk Maya is an industry standard 3D CG software used for animation, modeling, rigging, etc. You can find information simply through googling key terms
I don’t want this to dissolve into meaningless discourse, but jxzzify simply gave his input and there was no need to respond like that! He does have a valid point in that the objects are mere primitives, and that it doesn’t really showcase much effort.
Once again, I do recommend you look into 3D cloth simulations as it will help you immensely in getting the results you probably want!
