So far I think it looks great. The layout is very nice and easy to read. Sometimes it can be hard to get instructions to flow nicely, but I feel you have accomplished this with ease. You mentioned using pictures as markers only at this point. I do think that better edited pictures would help overall, but it seems that you are on top of this. A few more small pictures may help as well for people who are not as familiar with the use of the computer, but since we are assuming college age this shouldn’t be much of an issue. Overall it looks great.
