Also I've found that using various aspect ratios does not add artifacts, and that it does have implicit data e.g. most portraits are taken in... Portrait, and so if one is intent on fabricating a portrait, such an aspect ratio does, in my experience, tend to generate more favorable outputs. There are several other features that aren't listed here, such as tokenizing, weighting, AND, img2img, feedback... Textual inversion, and aesthetic gradients... Another way I've been fairly successful in, is using 1- or 2-step outputs to find a good basis for composition as you can generate a lot of outputs quickly and take the best of the bunch without waiting eons for your 16x16's to diffuse.
