In my opinion, typography is one of the most important parts of graphic design. You can have as many illustrations and photographs as you'd like, but nothing can quite be as effective as the proper usage of typography. For some, it comes almost naturally while for others it is a constant struggle. Dana Tanamachi has a hands-on approach to typography that I think would make my design professors proud. Her work shows careful thought in terms of stretching, skewing, and readability. I'm not a huge fan of her posters, but the hand-drawn type is great! For more about Dana, visit her site.
