Here is the original:

What tools/technique do you use to go from original to the edited one?  

You should know better than to post a picture on the internet and ask for "photoshop" help.

I don't know how to do the things I posted in op in Photoshop, so I asked for help and posted some picture examples. What's wrong with that?

I think he's referring to how there are people who will "help" someone with a photoshop edit when they're just trying to troll them.  

Oh. I apologize for the misinterpretation.

All I want to know is just the tools or technique used to alter an image like the one shown in op.

I know which tools would make sense to use but I just don't know how to do

This website is the one I use in my photography class, its pretty handy.

As far as I'm aware, it looks like the person cleaned up the edges, filled in the color and added more detail using brushes.

The additional affects could also just brushed on, nothing super fancy.
