yes that is all pen tool using AI cs2 i don't have a tablet that why i can't use any brush thank for your wonderful comment I really glad that you like it
I started that way too but I think with your skills using the pen tool you could possibly do the same thing with the pen tool, duplicate the line or make a similar one then use the blur tool combined with a puppet warp and come up with the same result as using a tablet. I'm somewhat new to vector illustration but I think it helps once in a while when I don't have my tablet with me.
