It's alright mistakes happens.

for the funnel exercise i noticed that the ellipses you made are extremely wobbly, good ellipses should be executed with confidence. try ghosting the ellipses for as many time as possible before you put down the mark you have all the time in the world to do this so please take your time and give it your all for every mark you made. In fact when i looked back at your exercises it seems that you were trying to get through the course as fast as you could, this is somewhat concerning, the point of these courses aren't to be done as quickly as possible; it is to teach you the ways of mark marking and to give us to visualize things in 3D. the chances of getting these goals would greatly diminish as you rush through them hence once you step in to the next exercise i highly suggest that you would take your time to make every single mark you make the best one you could with your abilities. This isn't a race, not a marathon even the creator of this course describe the journey you're taking as something more of a cross continental journey so take your time and dont try to rush it alright? Also try to incorporate the ellipses, ghosted planes and superimposed lines to your warm up routine you'll need to practice them a lot and maybe consider going over the lesson material again too there's plenty of pointers in them that'll help you tremendously.
