Nice work! I love the sci fi feel. I have been working on one point perspective a lot recently so I thought this may be helpful. If you draw an X in between the rectangle you are working in you can find the halfway point. Then you can repeat this as many times as needed. This is pretty simple if you are working on just the horizontal and vertical planes as the lines are straight. However if you are working at an angle, the lines must be parallel to the other angular lines on the side. I don't know how to divide the cushions into thirds but here is an example of how to divide it into fourths. You can also use this to find the halfway point on other objects such as the circles and checker pattern on the ceiling. Take this advice with a grain of salt please as I am very new and it may not be correct it just seems to work for me. I hope this is helpful. Also love this style!
Thanks for explaining your view on my Chinese couch (random inspiration), @leeireo. I was trying to indicate equal distribution. But yeah, I should used @Lockenheim solution to draw the couch in equal distribution.
Thanks for your awesome explanation on how to split the couch equally. That's something I and @leeireo didn't know but should have due to mathematics knowledge lmao. And no, the advice makes absolute good sense.
Btw, the orange and blue lines you draw are not parallel if I'm assuming correctly. That's the case, that's me doing work at 1am - brings out the worst accuracy out of me. XD
But I do appreciate that you read my blogs, @Lockenheim .
Nude Figure Drawing
Now, this is where the interesting bits is coming in. Drawing people is never my strength (excluding cartoon lmao) so this took some considerable times in comparison to other courses in term 1. But this is very beneficial as it strengthens my observation out on what to look for.
NOTE - There are a lot of good examples on Discord chat. Go have a look for more reference on there. My Discord is Gordon003#7031 if interested to chat to.
Part 1 - Line of Action
Part 2 - Head, Ribcage & Pelvis

Part 3 - Joints
Part 4 - Cylinders
Full Process Combined
Part 5 - Proportion

Part 6 - Gesture Drawing
Most challenging but also the most rewarding. I have done Gesture Drawing before but I don't see the main goal/point of doing it every day until Marc and other Youtubers videos recommended by other artist on Discord explained it.
Basically, it helps me refine my observation skill in detecting key body parts quickly and find the flow of action since it's meant to be quick. In summary, this one took some considerable time and will continue to do as warmup activity.

Overall
This is the hardest course in Term 1. But it's the most rewarding as it forces to work on my fundamental skill which was one of my art goal and reason to join this art school. And I'm happy to notice that I'm less rigid in my drawing and more fluent.
I like the improvement on your gesture drawings! The planes on the faces add a lot in my opinion. I try to do that myself but run out of time! Gesture drawing is also the hardest part for me as well. I also feel like it improves my speed considerably when working on other practice. Keep up the good work!
