I remember the good ol days of free hand trace.
If I traced or I had used pencil there would have been less imperfections than the pen drawing.
The biggest one is the shoulder pad and the location of his right arm. The shoulder pad is slightly wrong and the right arm is in a feasible position but compared to the actual photo, its too low.
The laser rifle isn't long enough.
The eye visor is a little big.
Etc.
I wouldn't consider it tracing, I started from the top of the helmet and just built it up from there, I used a pen so I couldn't erase to correct proportions either. I did obviously use the picture as a reference, so Bushido is correct.
