Hi Sawsan.
I'm trying to understand who you are trying to reach with this message & attachment.
I see "Course" - is this your answer/project for a PTC course, such as those found on PTC University? If yes, could you please let us know which one? We can try to redirect it to the people in charge of this course.
My other guess is this may be related to a course at an actual school (college, university, etc.) and you're trying to gather feedback on it. And possibly help to realize the actual project (not just the design). If that's the case then we will probably start by moving it to the correct section (Thingworx Developers or Thingworx Ideas) and also check if this is the best way to get feedback.
Let us know how you wish to proceed with this.
