For everybody who seems to be having difficulty telling the difference between G4 and G3.5, if the ears line up with the back of the head (roughly like a real live pony), she's G4. If it looks like she has a massive tumour at the base of her scull (large bump between the back of the ears and the neck making the head look generally swollen/bloated/over-inflated), she's G3.5. G3.5's snout is also more pronounced, but that may be more difficult to notice for people who are new to post-2008 ponies.
