well the first pic is basically just a version of one of the 3 pics in my signature.. I basically just drew the outlines and added a bit of a jawline to it and the mouth..
and the 2nd pic just has the jawline more visible along with some slight shading of the neck and a bit of doodling on the torso part..
and by now there's about 3-4 different versions of that very same drawing.. the only difference is the mouth and the eye really.. just experimenting with different types of grins xD
oh and btw, my signature pics all originated as this pic
basically my signature is just this pic x 3 and just converted into "neon" with photobuckets image editor
wich is a pic of me when I was bored and had nothing to do other than fooling around..
p.s. I suck at deciding on what to write so I always end up editing my posts several times.. already edited this post 4 times.. xD
