She looks really big but I don't like her shape at all, especially around the mouth area it looks deformed. Maybe she's just really old. Anyway just that size is impressive enough.
I don't like her face either. But what do you mean you don't like her shape I have never seen a stockier female gt? She give of some chunky, thick, tall body males.
I have been looking locally for a big female but no luck. Your girl is gorgeous by the way, good luck with her if you do decide to breed her should produce some great offspring.
