The moves look good! But is it a trick that you created?
A handling is where you keep the effect the same, and just alter the method (For example, performing the ambitious card, and substituting your own moves to make the card appear on top.) In your video, you have performed existing moves to execute four colour changes. If this is your take on an existing effect where four cards change to aces one at a time, then you have a unique handling for an existing trick.
A variation is when you introduce something new to the picture. If the original effect ended as in your video, a variation might include a new element, such as the cards then changing to a different four of a kind, or changing in a way that alters the core effect. For example, the four cards turning all blank instead of into aces. The pips of the four cards are then found in the card box.
A creation is a completely new concept or method, or a combination of a concept, method, and presentation that hasn't been put together in that way previously. Truly original creations in card magic are very hard to come by.
I think that what you have created could more accurately be described as a sequence.
Just food for thought!
