i coulda sworn you did have a tablet... or did it break recently? *scratches head*
@ Panacea - like get the lines to be smooth and dark? well the sketch is on a different layer than the finished lines are, the opacity of that layer is also set to 33% right now, and the finished at 100%. For paint tool settings (i never use pencil), i use default everything except for Opacity and Size :] for these lines 7 px size and 255% opacity (highest it will go) :} and pen pressure turned on (black dot/filled circle)

hope that helps, and yeah, im really having a hay day with these lines ^w^ (which means they will come out great) :p
Have you tried out for a WoI before?
