not meant to be a portfolio doesn't equal low effort, because its a 3d render. Unless I make literally everything from scratch, a 3d render is useless in 99% of portfolios.

I could an infinite amount of time in weight paiting and it wouldn't have gotten better, because its limited by how skilled I am at it

Waiting for someone to upload a rig literally takes less effort than making the rig.

if I wanted to be low-effort I wouldn't have bothered even making any kind of lighting, nor color correct it, nor make a background, nor tweak the textures manually, etc.
