To make the whole thing look a bit more "drawed", i selected the brush tool again and set the brush size to 5 and Stroke the path again but this time with the setting "Simulate Pressure" on. it looks better IMO =)
And now you're free to colorize the picture (Comic Style)
I know i suck in coloring =)
some usefull tips: you can save the vector image, Window -> Paths, just double click the Path Layer and you can store it, quite usefull
and to get rid of the Path lines just click in the same window as above^^ somewhere under the layer
I'm sure i forgot the important stuff as usual =) but i hope you're happy with the tutorial
