Hello,
Currently I’m the newest member, Yeah!
Not sure if there’s a forum for adding art to get advise. I see you can’t post an image so I’ll include my link. I’m one of a million who aspire to be a character developer and animator. I’m working hard at being my best but really can use some input on my 3d characters.
Thanks,
Marko
Welcome to the boards, marko! Good to see another artist here! 
You can introduce yourself in the main introductory thread, if you like- Hi, my name is…
And as the 3D artwork you’ve linked to isn’t Fanart, this is probably the best place to post your art and ask for some advice- Non-Pixar Art
From what I can see, it’s very good work! I know next to nothing about 3D modelling and that sort of thing, so I can’t offer you any critique, but I really do like your character designs.
