Very valid comment.
If you're showcasing artwork which you want criticised I honestly think no more than 3-4 pieces if you want detailed comments.
Anyway there's nothing particularly wrong with any of them but all of the concepts seem quite similar and you seem to be relying a lot of C4D's. Theres nothing wrong with using effects like that, but try to incorporate something different to develop your talent in other areas. When I make stuff I try to vary it... bit of c4d, bit of smudging, bit of photo manipulation, vector and so on![]()
