You will be pleased to know that I am actually using the Art forums to get design feedback that will hopefully improve my 3D Designs in B4Artists (a fork of Blender, and one I set to look and feel like Maya as much as possible since that is the "industry standard.")
Here is the link.
I may want to move to more 3D-specific forums like Blender Artists or Polycount once I get more comfortable with the fundamentals and want to compare my stuff with people actually working in Hollywood right now, but for now I think this 3D art thread is a decent way to network with the brilliant 2D concept artists here, and hopefully get to a point where I pay them to do designs and character sheets for me so that I can solely focus on implementing them in 3D.
Because let's be honest, if you want to do 3D art that is more polished and complicated than a few low-poly spheres and cones combined together with a basic rig to form a PS1-looking character, then it is a team effort, similar to developing GOOD indie games for the Game Portal or Steam. There is a good reason why the credits sequences for animated movies from Pixar, Dreamworks and Illumination are so insanely long, and even the straight-to-video stuff in Netflix's Kids section is also made by a team of hundreds--expensive-looking CG is made by numerous specialized working months or even years on a 3D asset you may not even be able to easily see in the final product.
I don't want to say this to discourage anyone, but this likely explains why it's so hard to find truly professional-looking art on NG, although I hope to be the one to raise the standard of 3D art on this site once I get more practice. Plus, to avoid burnout, especially if you don't have a large animation studio at your beck and call, there is no shame in keeping things extremely simple, so long as it lets you actually upload more finished projects and animations than if you spent years and years making your single character up to the standards of Hollywood, with fancy simulations and fur and the works, before FINALLY moving on to making the triple-A PlayStation 5-looking chair the character will sit on when you finally move on to animation 90 years from now. Especially now that lo-poly PS1/N64 graphics are in right now, and it is far easier and cheaper now to do lo-fi 3D in Blender than when the technology was brand-new.
Despite everything that has happened to the site since last December, ArtStation may still be the only place to find top-tier 3D artists.
