A good start, I can review drawings online during class.
some quick thoughts on improvements:
- you should add a heavy weighted that line indicates the ground level.
- the lines of your cantilever are too heavy
- you should add elevation markers to show the relative Heights of the building
- You do not want to use multiple lines for the curves
- Give at least 8 inches of thickness to your slope roof
- With a dash line you can add the outline of the Cellar level
