I don't know of any sites that have drawings or pictures of forms, but if you want to progress the best advice I can give is to listen to your instructor. He has been doing it longer, and can offer better advice than pictures can. Your sifu may have videos in his library as well. Also don't get too carried away with wanting to advance as quickly as possible. Instead of focusing on what color is around your waist, focus on what the form is doing. Just keep working on what you are doing, and soon you will be up to the "cool stuff". The sites that mention the movements in the forms will help you after you learn the form. But for the time being, focus on your material. That is the best advice I can give.
