Back to the topic, related to art. This goes back to how one trains their own brain, which is not separate from them. Here is another portrait, that I've been working on, but because it was a new scale, about the size in the middle of what I had worked on before, my brain needed to calibrate the form of a Human Being in this particular scale. So anytime one adds new spacial requirements for a creative outlet, depending on the priority assigned in the initial decision; which translates into how excited, determined, and resolved you felt to begin in the previously unfamiliar scale. All that plays a role in how you will embed whatever knowledge you gain from setting that intention into action. Keep in mind your first attempt is the one in which your brain is still creating spatial dimensions, and determining things like what an average mouth will be like in that scale, ears, eyes, nose, all those things are embedding themselves as you're working. Even if you have prior experience in the medium you are working in, and knowledge of the subject matter, the first effort in a new scale is also training the brain to familiarity with those spacial demands your intention set into motion. Here are two examples attempting to do the same portrait, which was a commission, and although the first one satisfied the client, I wasn't satisfied, because it fell short of the results I intended on producing, and I became aware through keen observation of the learning curb in the process itself, which as I mentioned in the past is my meditation. Below the painted bust is the first attempt, where my brain needed to calibrate and ratify all the spacial demands my intentionality set into motion. The second work is yet to be painted, but the spacial demands of working a this scale have been satisfied, I have created the bust with the torso extended down about 1/2" below the breast, this will eventually help with shaping the bodice of the dress for this doll.
The point here is I observed a limitation in how my brain operates when it comes to new spacial requirements, and the advice is if your creations are mostly creating in one particular scale, and you decide on working in a larger or smaller scale, it is natural that your first attempt regardless of all prior experience is also a retraining process for your brain. The preceding outcomes from working in a different scale will follow after an initial calibration of the new spacial demands which the first attempt will be dedicated too.
Final note; say a person who is a master at painting miniatures, decides one day to paint large wall murals, the first effort, presents a learning curb for the brain. Technology can re-scale an image or three dimensional object perfectly, and it's wonderful we live in the age of technological wonders. Our brains are not perfect machines, and all though some of the process in creating is mechanical, it is the malleability that is part of human nature which is the water of life, and it can play a role in attempting something new, you don't drown when you are water, so as Bruce Lee famously said "Be Water, My Friend."
