So yes I have experience doing all the thing you listed above ^ and what I can tell you is that yes, photoshop and editing are a bit hard to do at first. It takes awhile to learn and perfect it all...but once to get the hang of it, it becomes extremely easy to memorize and use actions/filters, things that are pre-loaded into PS that someone else made so that you can easily make your screenshot look cool.

The photos I took above took me an hour max, the hardest part actually coming up with an idea, or waiting on quote on quote 'perfect weather.

Now as I said in my earlier post, I agree that if you spend hours upon hours editing, your edited pic is a piece of art. But what I will say that as someone that has dabbled in all the fields you've stated, Digital/Real Life art is STILL the biggest challenge for me, and I give anyone that has the patience or mentality/talent to draw a huge thumbs up.
