Advice for Concept Art Portfolio

US Claire Force

Hi! I used to be a 3D modeler and graphic artist for a simulation company, but the department I was dissolved. I'm trying to make it into the games industry (either print games or video games) as a concept artist. If you could look at my concept art portfolio, please let me know what I can do or change to make it better.

You should invest more time into studying art. First get good at art, then think about concept art. You can't design things without knowing the art fundamentals, meaning drawing (perspective, line quality, proportions, form, values etc.)
Read a lot of books and learn from master artists, take courses, do whatever you can do. If you have an atelier in your area, I strongly suggest you go there.
If you don't feel strongly about investing most of your time into art, you should decide what you want to do ultimately. You need to specialize in something and if you're decent at modelling and enjoy doing it, you should keep doing that.
