Congrats on finishing lesson 7! I'l do my best to give you feedback so that you can improve.

Starting with your form intersections, the intersections themselves look great. It looks like you've experimented with different surface interactions (round-on-round, flat-on-round, flat-on-flat) and are comfortable with all of them. The main critique I have comes from your line work which is looking sketchy/choppy so always make sure you're drawing confidently from the shoulder. Also just a minor note for the box in the top left, make sure you're drawing through all your forms.

Moving on to your cylinders in boxes, you seem to be applying the line extensions correctly, just be careful for the back corner because it seems you forgot to extend from there. Also it seems like your box lines are sharp and crisp but when it comes to the ellipses they start to become deformed likely due to you trying to fit the ellipse inside the plane. Remember that it's vital that you have a confident line first before you focus on accuracy of the ellipse.

For your vehicle form intersections (which I'm going to assume is the first page) you've done a good job sticking to simple primitive to build up the vehicle. This exercise is just meant to remind you that in the end we are just working with simple primitives no matter how complex something looks.

Now onto your vehicle constructions. Your work here demonstrates developed spatial reasoning skills and it's pretty solid however this critique will be focused around the fact that what we want to confirm through the assigned work here is not specifically that your spatial reasoning skills are solid, but that you're demonstrating a clear understanding of how the constructional drawing exercises we employ here can be used to continue improving upon the spatial reasoning skills you currently have. This means that any situations where we might use our existing spatial reasoning skills to skip steps and speed up the process works against this goal. That's the main thing I'm going to address here.

Now ironically you've used more precision by utilizing the lesson's techniques in the vehicle form intersections rather than the vehicle constructions themselves (which is what they were meant for). You still have used them just to a much lesser extent which can be seen on image 3 and 5 but for the rest of your vehicles you either apply a loose grid or plane in the middle and end up eyeballing it from there (which you do a great job of doing).

Because of this I'll ask for 1 more drawing (if you're still using this site). This last drawing should be done using a ruler and you should use a car / bus for the reference. Also for this last drawing you should include orthographic plans and proportional studies. If you are confused about what they are check this students work out they are the drawings that precede the vehicle constructions. In sharing this work my aim is not to set a level of expectation for the work or for you to compare your work to theirs it's for you to see how you can get the most out of this exercise. Also in this drawing try to avoid form shading on the windows / wheels etc. as this course only focuses on cast shadows.

Now you can clearly draw very well but the point of the last lesson is for you to develop your spatial reasoning skills further and not to draw appealing drawings. If you have any questions or need clarification don't hesitate to ask!
