Alsoo, in case anyone's wondering what I did on the line art I basically did the next thing;
1. Duplicate the line art 3 times, and then change the colors of each duplicate to cyan, yellow and magenta

(do not move them, this is just the example)
2. set these to multiply, which makes it so when they stack on top of each other creates the comic inked efect

(again do not move, this is just how it'd look like.)
3. lastly, move the blue layer a tiny little bit to the right, the magenta to left and down, and yellow to left and up. The result, without the main line art on it:

and this is the end result with all four layers

It is subtle, but I think it gives a bit of personality.
