it can be specific to body features common with being trans or just general photography technique in general, no matter how basic. example photos are ok, but we do not demand them. just thinking this would be a helpful thread to have !!
a tip of ours (for those femme-leaning at least):
having the camera from a more top-down perspective seems to make the jawline look a little nicer. this is true of most others in that they look skinnier, but it especially seems to bring out the femme look in our experience.
Try in different light sources, especially when wearing makeup.
Especially with LEDs these days which generate very specific wavelengths of light rather than wider spectrums that incandescent bulbs emit, artificial lighting often changes your look. So if you can, try some natural lighting, or use a light source that has both cool and warm LEDs as opposed to one that has just neutral LEDs.
You’ll find different color light sources bring out different colors on your face and cell phones try to correct for that, but most don’t do a good job and end up making it worse by overemphasizing certain shades, IMHO.
