The "enter" picture's file size is a bit large, use file>save as for web in photoshop to fix that problem... you should be able to get it down to somewhere of half the file size it is right now. The same goes for your main logo which is a big hard to read. The light blue text is also a bit hard to read... but thats not really much of a problem. To be honist the only magor problem is the un-nesacery file size of all the pics. You could save probably a bit by making some of the pics in your ps tutorials as gifs. A back to top link at the bottom of your tutorial wouldn't go astray either. I like it
