Viewed from this angle, characters would look almost "chibi" with all the foreshortening. You're showing too much of the legs and abdomens, and not enough of the tops of their heads and shoulders. The reason it looks like a front view is because it is a front-view, just one you squished. Bodies are 3D, and in this view we should be seeing the tops of things. For example, the overly-defined abs on the man are drawn as if they're from the front, they're not curving around the body. The man's pecs aren't overlapping any part of his body as they should, etc. Think about bodies as 3D forms. They have bits that stick out and parts that go into the body. This means that things can look quite different in 3/4 view.
I recommend giving Loomis's Figure Drawing book a read, I'm sure you can find a PDF online for free, those books are long out of print. I think there are even some examples in them that are quite close to RPG view, just upside down. Most importantly though, he talks about the important parts that get "distorted", and that's what you need to learn. Actually read that book, don't just look for the relevant section and diagrams.
