So I thought I'd be a helpful nice guy and offer up advice and answer questions to anyone curious about going to an art school. I'm currently an animation major, and I received a PHAT ASS schola-sheeip just for my PHAT ASS portfolio. So if you've got some art and you want to know if it's up to snuff from someone balls deep in college than you should do yourself a favor and ask me. Post links to your work and I guarantee I can tell you exactly what you need to do to improve. Any other college related questions are welcome.
First some general tips.
1. Take a good hard look at your finished work and/or sketchbook (you'd better have a fucking sketchbook)
2. Realize that you suck
3. Figure out why you suck (ie. compare your stuff to professional work)
4. Trade out bad drawing habits for good drawing habits
5. Repeat steps 1 through 4 until you suck considerably less
Seriously though, people tend to develop "style" before they develop technique and then they get married to their "style". Having a unique look is huge but it can stifle your growth early on if you refuse to break from it. If you don't believe me go look at deviantart.com, the worst stuff typically looks like the same shit (furries, anime) over and over again. So don't be a fucking anus about trying something different. If you see something you like that isn't something you'd typically do, take a crack at doing something similar to that. And don't huff and puff about originality, everything you do until you get a job is practice and experimentation. Your originality will multiply every time you learn a new technique.
Besides that, get used to planning stuff out. Don't just dive into something you're planning on spending 5 hours rendering in photoshop. Take a half hour to draw 5 small versions of what you want to do, or 10, or 20. Keep going til you really think you've got something you like, then make it big and clean it up.
This is by no means a comprehensive list of suggestions but if you're not already doing these things you need to. Again, I'm willing to answer any specific questions related to anybody's stuff, so ask away. Or if you're a hot shit artist and would like to add something feel free.
