I once received an incredible portfolio from an aspiring designer full of clay character sculptures. The work was stupendous and it was clear that he was super talented but the problem was that I run a graphic design studio where there was no need for a clay character sculptor. I advised him to try gaming companies instead or maybe even special effect studios who have a need for this skillset.
I receive some terrible portfolios from rookie designers but it’s not actually your fault as a budding designer.
The terms graphic design is actually a pretty general and broad term covering many industries and disciplines with a cross-over of many roles.
