Ive chatted with him on emails when he showed me how to do some of his modeling techniques. Of course though, the modeling isnt the hard part and now-a-days hes importing CAD files so thats why alot of it has gotten so much better.
His by hand modeling was pretty crappy IMO. But hes a wonderful artist and makes up for it with great scenery and even better animations. Especially since hes developed his own scripting though it still needs some work
