I had fun working on this, I'm a sucker for t-rex, and I think they areadorable despite their appetite for meat, so here we are, starting witha sketch, and filling it up with a pigment liner pen, for this I used.1 to .7, .1 is good for capturing details,it's also better if you getthe .05 one, you'll never miss every single detail on that.
Sofor this linework, I scanned it up and tweak a bit of the tones therein photoshop, to get the right contrast, so it will make the lineworkcome out more,and delete other unnecessary ones.
