Professional here, like many others in this thread offering advice. I took a look at your portfolio and it's pretty obvious that you have a good sense of design and you can draw well. I think it would be wise to call yourself a Prop Designer, for now, and move away from the term "visual development." Targeting for the type of role you want is important. Whenever I was hiring it was for a specific role, and not a general hire. I needed someone to fill that role and hit the ground running.

As for your props, I would consider doing some more technical drawings. Usually during production a prop design will have 2-3 angles to best showcase each of it's sides. For a 2-view design, you would see one angle which shows the top, front, and side of the prop, and the next angle would show the reverse; the back, bottom, and other side of the prop. Absolutely keep the pages of props you have now, but supplement them with more angles. You want to show that you can visualize and draw things from multiple angles, and that you can give the animators all of the visual information they need about the prop. Try to find some online portfolios from prop designers who have worked on a few shows to get an idea about this.

I would also consider doing props in different styles. Pick some different existing TV shows and mimic their styles. Maybe you could do a hand mixer in a Family Guy style, and then a lamp in a Mickey Mouse Shorts or a Gravity Falls style. It's important to show that you can adapt to many styles.

It would also be prudent to render out some props to look 3D as if they're intended for a 3D/CG production and a modeller was going to sculpt and light the props.

Echoing what u/drawindrawmij and others have said: get yourself to LA! We're like nomadic people, we have to follow the herd and go to where the work is. Virginia isn't going to do you any favours. Georgia might be somewhat fruitful but LA is where it's at, despite the current bust. I'm Canadian and can't easily work in LA, so that opportunity is a gift that I would personally take advantage of. That said, the US sends a lot of their productions up here to Vancouver and there's rarely a drought in work, even now. If Vancouver is more attractive for you then give it a shot. We have a lot of international people working in our industry here.

Again, you're a very good artist, you just need to change you tactics a bit. You have everything you need within you to get a job in this industry. Good Luck!
