All in favor of posting more, hell even post in the resource section (I nice necrobump in any of those threads would be like a life boat at this point.) say "I"
Break it down into showcases. Smaller showcases, guys remember digital applications to even Photos. So far, GG, HH, AJaxx, Pablo, and Jackie have really been the only major photographers/manipulators, Trigger as well.
Larger Showcases
Typography, showcase Font Face applied for posters.
Photography, showcased in basic photo manipulations of which isn't just limited to Color Corrections (got a CS2 Format book on this actually), Additions/Replacements, Scrapping/Mosaics
Digipanting/Speed painting/Paint Tool SAI into a showcase, if you want a reference more so just a general combination of TM into DM, or usually not entirely the same, done from scratch often.
Illustrations into a showcase. Actually, Illustrations come something as a combination of both painting (more or less) and digital applications. Things are smoother, as far as the actual program its a tool that works with images, shapes, and colors that don't deteriorate in terms of dimensions because only one is provided and it doesn't change no matter what shape, or size.
^pretty sure we didn't cover this yet, If i've left room for error, swoop in and capitalize&punctuate fellows/ladies.
