There's so many variables when learning new things....that we can get lost in all the new possibilities.

I would recommend trying to improve the images by making them look as normal as possible....proper exposure/composition/focus. 1/2 of these images are too processed imo and have additional issues w/focus/exposure.

Post-processing is a whole other beast that offers an infinite variety in how the final image looks....but it's yet one more humongous variable to learn and it will rarely "save" an image.

Hope that may help. - Marko
