Joomla! Integrates
perfectly with other
tent within my site.
-Autocorrect capitalized "Integrates" for you!
-On the front page, "Joomla! for Personal Sites and Blogs" is a bitmap, whereas the rest of the text is real text. If at all possible, you should make it real text, as it looks awful if you even zoom only to 150%.
-You may want to use a site other than the "Why Joomla!" site. It would be best if you could use one with a fancy template, because many people are probably looking for appearance as well as function.
-If at all possible, I would really like it if you increased the image resolution. Modern printers may make this look pixelated. I have a B&W laser, so I can't test it. If you have a color inkjet, it may be a good idea to test it. Having pixelated images would reflect poorly on Joomla! and make Joomla! look... (dare I use the "C" word?) cheap.
-For your final, you will also want to get that blank page out of the PDF.
Nice work!
