heres a picture of a panther ive done with the Ambush cammo
it can look anyway you want
theres another good picture of a Ambush pattern here
i dont know whose it is but i like it
you could do a grey and green camo as was used in Berlin in 1945 or you could try vertical lines in the three coluors red brown , dark green and dark yellow
play around with the camo paterns to see what you like best
