Hello,
I'd definitly say "no" : she doesn't have a Bengal look at all
.
However, she may have some Persian blood I guess : short nose, rounded head and long fur are more caracteristics of this breed than of the Bengal
. And the blotched tabby pattern is common in all cats, the Bengal having his own variation (like rosettes instead of spots) which is the marble pattern (3 colors instead of 2).
A spotted stomach doesn't mean anything as it is common to a lot of tabby cats.
Sorry to break the hopes but remember, there aren't a lot of breeders letting their studs stray and a lot of male cats owners have them spayed to keep them indoors, so the hopes of having an "half breed" cat aren't really high
.
Breeds (except for the Bengal of course...) were often created with "moggies" ancestors having some special caracteristics that some people wanted to keep (I'm thinking of the Rex cats, Bobtails, Norvegians, Maine coons...) so what you probably have when you have a cat reminding you of a breed is an "ancestor" (a cat that could have been used as...) more than a "descendant" (for such caracteristics as long hair by eg... I often see people asking if their cats are Maine Coon or Norvegians just because they've got long hair !).
For some common breeds that were created long ago and very popular yes I guess there's some blood runing around in the moggies (thinking of siamese and persians) but for the Bengal (at least in France for sure)...
I took Onyx because he kind of looked like a Bengal, but I know he's not cross bred, he's just a brown spotted tabby (pattern quite common in tabby cats) that happens to like water (I knew a type Siamese when I was young who would swim in the pool ! that's not so rare) and be talkative...
For dogs it isn't the same : people will more readily buy a breed dog than a breed cat, and they aren't always spayed (not needed for in door keeping, and some men have an anthropomorphic reasoning... at least in France where dogs aren't sold spayed) so cross bred are much more found.
Sorry for this long post but seing so much people asking, I wondered why did they want their cat to be half Bengal and what could make them think that when they didn't look AT ALL like one ?
Edit : some photos of marbled bengals for you to compare :
