i myself don't wanna sound like i am hammering you, however, still very excited to see final work.
my point is, if ID had trailers out already and kickass editing done for those trailers, just trying to figure out how you jumped in there and he shut his down. if he lost work due to a cpu crash, i understand, that sucks. however in 2 yrs, and the best we can get is a shotty ruff draft from you, then i would assume, maybe you bit off more than you could chew?
again, no offense, just making the case, if you volunteerd to continue his work but with a twist, and after 2 years, i would have let him redo his, if he felt like it, because i'm sure in 2 years time, he may had enough push to start again and be done by now.
