Here is the last old pic (from 2006 most likely) that I have to upload if I recall right.
I drew this after reading one of the Halo novels - I think it was First Strike. (Nylund FTW!) - it was when Kelly reunited with Master Chief by approaching him and lifting her fingers to do the smiley sign over his faceplate.
This is the Spartan II version of a super glompy hug of OMGMISSEDYOOOOOU!!!**EDIT MARCH 2010**
Did a color 3D picture of this!!! I am stunned beyond belief it's so awesome! Check it out here: [link]
