Practice on memorising a card deck.

Arranged a card deck in order.
Looked at a card, closed the eyes, pictured an image and drew the image of card on it.
The problem is I cannot think in 3 dimension if it is not in loci. Is it normal?
Learned the image of each card. Realized that Do not have to see the entire card, but just the part of it.
Saw a card, closed the eyes, pictured a jpg file of each face (I am using Dominic system) and painted an image of each card on each file.

After completing, only the image of Halle Barry (Heart 2) remained.
The goal is to see the image as soon as I see the card.
