Got a new upgrade for my ZBrush. It now does 64 bit support, which means ZBrush now uses more than 4GBs of Memory (I've got 20), and so a higher poly count/detail level can be reached without slow downs or crashes.
Decided to redo the Xenomorph as a test. I think it came out looking pretty good! Background isn't too bad either. Tried a new method and it worked fairly well.
