The answers to your questions are complex, and may be found in the links in my sig called "Concept Art 101" and "games industry".
I think you are awesome, and I wish you the best in your endeavors, but I am tired of repeating myself, I am very busy with my new baby, and I am no longer a regular participant here, so please do not contact me to ask for advice on your career or education. All of the advice that I have to offer can already be found in the following links. Thank you.
First off, you need to explain "industry-related." As far as I know, there are at least three different types of industry jobs: Fine arts, illustration, and design. For each type, there is a different protocol. I am more familiar with the fine arts presentation:
1. Always have a professional looking website, complete with business cards and a logo. If possible, its good to turn yourself into a company, if not legally at least on paper.
2. Have a series or body of work presentable to the client. If the client is a gallery (as most fine arts presentations are) bring a professional portfolio containing prints of your work, and if possible, bring actual paintings/drawings/ sculpture/installation shots whatever.
Anyone else wanna comment? I'm just a recent grad, I'm not that versed in professionalism, besides what I've learned from the career center at school
How silly do you look with butterflies flying about your head??
