no problem, you deserve it.

the background with the Moxxi looks too overly exposed and lacks a lot of details, you can train by playing with the adjustments by yourself and see different results.

About the character and the rest, I used the same Posterize effect to make strokes across the character itself and nothing more, just minor color tweaks. The most work was with the texts and specially making them look realistic, but it's a quite long story.. and need Ps for you to have, in order for me to be able to explain you..
