Roberto, well done, you've made a real impact on the work you need, and you must keep it up.
This is a checklist to make sure everything is in place for the preliminary site:
Using a camera introduction
Photoshop your picture/s and post to blog.*
Research on four school websites: 400 words short essay.
Survey - the survey must be given to 5 -10 people and the results posted on your blog
Catchup, including survey, annotated websites.
Draft brief for preliminary site.
Photoshop, first artwork*.
Setting up iWeb*.
Working in iWeb*.
Finish your initial site, and continue in your own time*.
*If there's an asterisk, it means you can only do this in school because of the software (unless you have a Mac at home).
Check the list, and fill in the gaps. I think you need to catch up the Photoshop, the sketch and the survey.
