I dunno... I'm with Ian on this one. The trees look like they were dipped on white chocolate instead of having been exposed to the elements. Despite residency in Southeast Asia, Googling winter trees and scenes is pretty easy. Basic in fact. I don't live within a thousand miles of a thick jungle, but my internet access can take me there for decent reference.
Even though the construction of the Panther appears to be very good, the slopped-on snow effect detracts immensely, for me. I think Art Instructor could do much better. Sad thing is: after having looked at his work over the past couple of years, it seems to me that AI has lost any love for modeling.
The ground work snow effects look pretty good, if not a little too "clean".
Plus, I believe Ian lives in an incredilby snowy part of the states, so I will trust his judgement.
