I have often seen so-called "tutorials" or "memes" on deviantart.com, which explain step by step how a picture is created.
I also felt like doing something like that and here is such a tutorial (teaching program) about my last picture "Mika x Zorro". :)
If you have any questions or if you want to know more about a certain step, just ask me. ;)
I actually think or hope that the pictures explain themselves and that I don't need to post an eternally long novel here. xD

Some information about the tutorial:

Time required:
- Sketch 1/2 + outline -> 1 hour
- Coloring -> 2 hours
- Background -> 2 hours

=> 5 hours in total

Utensils:
- Faber-Castell colored pencils (beige, dark orange, dark pink, dark green, brown)
- Toppoint colored pencils (dark yellow, orange, red, purple, dark blue)
- Toppoint pencil HB (for the sketch)
- Lerlitz pencil 2B (for the 2nd shadow)
- Faber-Castell ink ballpoint pen 0.4 mm
- Staedtler Cool Roller 0.2 mm
- Toppoint eraser
- Sharpener

Sorry that I didn't use any technical terms for the color names of the crayons, but I don't know the correct names and that's why I give them names that are so easily used. ^^ "

PS: Another sorry that the caption on the picture is in English, but I also posted it on deviantart.com and the English language is the alpha and omega. XP
If the resolution is not big enough, you could see the picture a little bigger:
