Nobody is really telling you how to improve but maybe it was the way you came off earlier..
Photographing is not all about pressing the shutter button. Its….
Iso, shutter speed, aperture, exposure , white balance
lighting, reflecting light, dof, raw (do you use it?), metering, focusing, focus points, composition.
Probably missed more technology stuff
running a business, working with people, poses, paying attention to detail like the background. the weather and how to work with the sun and shade, getting real smiles vs fake smiles, the location, the clothes, props, getting different angle shots, must have shots, post processing and marketing.
its probably more but my head hurt from thinking. Basically its just a lot to learn.
