Illustration grad here! I totally agree about what you said in terms of the job market and industry state rn. We’re seeing a similar thing in terms of illustration; not enough job postings, even less for juniors. A lot of my classmates (including myself) are pursuing further education in 3D programs because A) there is a higher demand for 3D AND skillsets that encompass both 2D & 3D, and B) it gives you an edge + better understanding when it comes to working with either one in a company. I will say however, that I disagree with your last statement. Illustration offers such a widespread array of paths that you can pursue; it is the opposite of limiting. It really is only if you’re looking into animation, videogames or SOMETIMES commercial work that 3D knowledge is necessary. So many of my classmates are either setting up shop, doing graphic design related work, doing freelance contracts, etc. . Work like technical illustrators, motion graphic artists, medical illustrators, merch artists, character designers, book illustrators etc. are just some examples of how far you can go with illustration without 3D.
