Your cat is definitely NOT Siamese. I can't tell eye color from the picture, but my best guess is that it is either a Birman, a Norwegian Forest Cat, or a Siberian. Most likely a mix of one of these breeds and a domestic shorthair.
Many breeds have 'point' patterns and yes, I would say yours is a Flame Point, but not a Flame Point Siamese.
He is a cream point. He is not a dark enough red to be a red point but if you are registering him then you would want to check the color options because some registries do not have cream point as an option. I register my cats with TICA and they do have cream point.
