wow you did an awesome job, i don't have much to say about this, try adding some shadings on your boxes, cylinders, cone and pyramids. it's not really that important but it's worth it and makes it more easier and makes you understand the side facing the viewer. this is really awesome, keep it up and don't forget to drop some critics on mine we can help each other by doing this. wishing you good luck on lesson 3.

and also i forget to say this, i don't really know if digital drawing is allowed for the assignments. but I'll check it out for more information and please you should also confirm it, if it's allowed
