Please help I don’t know where I’m going wrong

I’m making an attempt to covert a plan view into two-point perspective whereas utilizing a circle to set the rotation of the dice.

I’m following this video https://youtu.be/fwOgS7J0m-k?is=4NlMWgResYjoZ3xQ from the 6:31 minute mark.

My dice doesn’t look appropriate. I feel it’s as a result of these two units of traces don’t match:

1) traces which can be projected from the edges of the circle in plan view upwards

2) The traces projected in perspective view from the 1m measured traces sideways to the established x and z vanishing level on the horizon line

( each 1 and a pair of mark the vertical line of the edges of the dice in perspective, however they don’t line up?)

Any assist and steerage is massively appreciated. I’ve been banging my head in opposition to a wall for two hours now haha
