Your illustrations are good, but what are you marketing yourself as — an illustrator or a graphic designer?
You wrote that you’ve applied for “countless graphic design internships and jobs with no success,” yet your portfolio contains almost no graphic design. The few pieces of graphic design that are there seem to have been tossed in for the sake of having them there, but it comes across as though graphic design isn’t your focus and that you’re not especially interested in it.
It’s extremely difficult finding regular work as an illustrator. Once Photoshop, digital photography, and cheap stock art came along, the demand for illustrators dried up to a trickle. The cost of paying an illustrator for two days worth of work when a $15 piece of stock would do the job, just sort of shifted most everything away from illustration. Most illustrators I know are exclusively freelance and only hired for piecemeal work. My wife is a very talented illustrator who successfully worked for years in the field, but no more — nobody’s hiring. She finally went back to graduate school and got a degree in something unrelated to illustration.
In various jobs, I’ve been a creative and design director, and I’ve seen hundreds of portfolios from students and professionals looking for work. So from that perspective, as I said, your illustrations are good, but…
If I were the one interviewing graphic design intern candidates, and if I saw your portfolio, I’d likely not interview you for the simple reason that it contains almost no graphic design. You have a very well-defined illustration style, but unless I needed an employee with that particular style of illustration who dabbled in graphic design, I’d likely hire someone else who focused specifically on design. If that person dabbled in illustration, that would be a bonus, but an illustrator dabbling in design, um, probably not.
Your work is good. You have talent, but if you want to be a graphic designer, you’ll likely need to focus on that if you expect to find work.
