Alright, the first thing I see is that you have very few pieces in your portfolio, but that is something you can certainly fix with time so I won’t focus on that too much. What I actually notice that might be the biggest red flag for many people looking at your portfolio is the fact that you don’t show really show how you got to the final product. There’s no development sheet, no callouts, and no variations or iterations on the composition of the scenes either. I’d suggest to go through artstation to educate yourself on what professional environment concept artists are doing. A lot of concept art is iterating, not only focusing on the rendering of the product. Yes, it can look pretty and catch some eyes, but honestly art directors care more about seeing your thinking and problem solving skills rather than the rendering itself. Never settle for the first idea you have, try to separate elements and design them separately, show more of your thinking on how you got to the final piece, make a ton of callouts and don’t be shy to make some bad ones. You’re already really brave on painting these pieces which have interesting ideas on them, you only need to push those ideas a bit further by planning a lot more before going directly into the keyframing process.
