Like the new poster style , nice work
As for Graphic Teachers, Ive had more than my share of experience with them. At the end of the day if its not their thing, not much you can do about it. Just know theres an audience for everything so keep pushing your stuff online etc.
If your doing stuff for grades, remember the teacher is your client and you do your work based around their needs, just as if you we're being paid to do it as a job. Youll find your marks go up if you think this way. You might not like the work but its not about what you like, its about using your skills to make the client happy with the end result.
I never took this route
until near the end of my educational life but I was happy with what I did and the extra stuff I threw into my portfolio that I did for myself (in your case Boxman) opened more opportunities for me (along with the grades) because they could see when I spoke abut it, I loved what I had created.
Keep posting your work matey its great stuff.
If you like what your doing it will help develope skills without you knowing it; that will come in handy without you realising. All the work I did here in the fan base helped me understand webgraphics and improve my illustration skills, two things that have come in very handy over the last few years.
Thinking about it this way - I have alot to thank Gondee and Merq for
