There are many different areas to get into with Graphic Design. I myself am in graphic design school and have been exposed to the many areas that come with being a graphic artist.
1) Designing marketing and other materials (Posters, signs, business cards, resumes, invitations, books, magazines, etc.) 2) Branding - Creating logos, word marks, monograms, and company related correspondence, etc. 3) Printing - Layout for book and magazines, colour coding for print 4) UI/UX design for apps and video games 5) Character design 6) Typography (creating typfaces) 7) Web design
A lot of possibilities and ways to make your mark in this industry :)
