During university I started out with very rough ideas of what I could do or where I could go so the main goal was to find what it is I enjoyed. Within the 3 years I decided to specialise in concept art, including characters and landscapes. My current style is more line-art focused using cross hatching and pen marks to create texture and depth. I tend to stick to using pencil and pen with the occasional brush pen and ink, although I have been trying to get into digitally creating work recently on Adobe Photoshop.
As for colours I would say I tend not to use them. I usually focus on black and white images, sometimes with various tones of gray, but when I do use colours I like to use toned down, unsaturated colours to create a more atmospheric feeling in my work.
During university my biggest accomplishments are being able to experience working on a live brief, and getting to know more about how the industry works, but most importantly finding out about the other possible routes I can take in my artistic career.
