Hey Natalia, You have a really fun style and sense of storytelling! Don't make the mistake of thinking you need to master 3D to work on video games. It's just a tool like anything else, and can help you with your ideation. But it's great ideas that are important! That said from what I'm seeing in this portfolio you tend to lean more towards designing for animation. Seeing what you can already do, I would consider gravitating towards a specialty. To increase your value as a designer and a creative thinker in the job market. This will attract recruiters and art directors to your portfolio. I would suggest you expand on your world building with that in mind and showcase what you love to do. On a techincal note, I think you can really benefit from improving your lighting and material indication skills. This will help you sell the believability (not realism) of your designs. That said, keep up the great work!
