You probably haven't gotten around to it yet, but the engine exhausts of the AH-1Z are much wider and sticks more out than on the W.

Or from a model which shows more detail:

The wings should probably be bigger too.
Just some tips.
Keep up the good work

Ahaaa yes,,thanks Arneh,
I've got these same pics,,I plan to do the things you mentioned...
The wings are much larger,,,I fooled around with repositioning the Hellfire racks,,I can move the racks,,but will need some assistance to make em fire correctly from the new racks location...
Then the AIM-9's are a horse of a different color,,,I would think some major coding work to make them active..
