Real mark?

[rgomes10]

Hello everyone!
I need some help with this, please. The mark is very convincing, but the shape is strange.
Many thanks.
Best regards,
Regina

Yes, looks fake to me. The shape is not visible clearly in these pictures, but the mouth type would be present only on a type of item that has its sides go more or less straight down. Here it seems the sides are inwards turned below.
The blue lines look as if they were printed, not hand-painted. The filling colors might be hand-painted, though.
And really, the coloration is odd. If it were doucai ware it would not be of enough quality, and the base/foot rim would differ.
