Hi @CelticCoco, thank you for another very well made and presented tutorial and thank you for the acknowledgement and name check 
You asked for any corrections to English terminology:
2:14 The correct form is “Bird’s Eye View” and “Worm’s Eye View” (Eye is singular).
6:58 It’s “Two Point Perspective” (‘point’ is singular). You did get that right earlier in the video at 1:52.
At 5:32 there is the confusion between ‘vertical’ and ‘diagonal’ lines. I think a better word is ‘radial’ lines since they radiate from a point.
(The word ‘vertical’ would be appropriate if the VP was being used to construct the vertical edges of a building, but the lines would still be ‘radial’, coming from the VP.)
Now for the rest of my comments:
At 4:45, you mention that you can ‘modify the assistant with the handles…’.
However, you don’t explain that the VP centre is defined by the intersection of the handle lines.
As such, this is a very useful technique for fitting a VP assistant to an existing image or photograph in order to add or extend the content.
It’s also useful for checking if the VPs in an existing image are consistent and realistic.
Maybe this could be explored and demonstrated in another tutorial some day?
At 5:30, you use the freehand brush snapped to the VP lines to draw the railroad tracks. You start from the VP itself and draw outwards from it. This method makes it difficult to precisely adjust the angle of the assistant preview line. It’s better to start the line away from the VP and draw towards it.
At 6:10. you draw horizontal lines with the line tool. This is easier and quicker if you press and hold the V key to switch from the freehand brush tool to the line tool, click the mouse (or touch with stylus) to start the line and then press and hold the Shift key to force to line to be limited to +/- 15 degree steps.
Maybe that is too much information for a tutorial that is aimed at beginners.
7:00. For two point perspective, a new Assistant tool is being developed to do that:
Call for Testing: 2-Point Perspective Assistant
So an update to the tutorial series will be needed in the future
In the two point perspective section, I was surprised that you didn’t use a parallel ruler assistant to help with the vertical lines but later on you did say that the tutorial was aimed at beginners and that you’d deal with the ruler tools in the next tutorial.
After only a little bit of thought, I realised that planning and making a good video tutorial needs a lot of time and serious work so I decided, a long time ago, to never make one.
You have my respect and thanks for making an excellent tutorial series
