Well the obvious answer here is to go back and update the work you did with your newer, better skills. In our program we have to deliver an updated portfolio every other semester, and the profs make it no secret that any projects which could have been executed better should really get some post-presentation attention. For instance I have gone back to make a series of simple "shift" diagrams in some of my projects using SketchUp + Photoshop to make the design moves more obvious.

Unfortunately its the back end of December, so I'm guessing you probably don't have time for that. Ultimately I would include the work, and make it look as presentable as possible. That doesn't mean cramming every diagram or sketch you did into 2 pages, but making a clear and concise walk-through of the process you used in the project.

Thanks BenC, That's what I was thinking.

There are a couple quick edits I made such as fixing a perspective now that I know how to draw in perspective. The real issue will be telling the story without being able to give full diagrams. I.E) my construction docs suck. Almost no line weight, and some smudges.....won't be using those. Thanks for the advice, I really appreciate it!
