thanks a lot for your time @malcom I really appreciate the feedback!
Since I have zero experience in concept art industry, I would assume my first hire will be a small studio, so I tried sprinknling a few characters in there, maybe I should put them all in one spot, at the bottom.
As far as finishing pieces I agree, they could use more polish, I often get anxious towards final stages I will discipline myself.
Again, thank you very much!
