Thanks,I did'nt understand much of that centre of mass thing at first,but after flipping the image I see that she really is leaning back a lot.I still don't understand completely how the centre of mass actually works,but I suppose I might be able to fix it.

Flipping the image is a good way of checking it.

The centre of mass is an important concept to understand, though, so I'll try and explain it.

Imagine a flat shape which perfectly fits under both feet, but also covers the space inbetween, a bit like an oddly-shaped board. This is called your "base".

The centre of mass is just a point roughly in the middle of an object that can also be thought of as the "balance point". Gravity acts through this point.

Because gravity acts straight down, imagine a line vertically down from your centre of mass. Let's call this your "weight line". Now, obviously, this line will go past the floor at some point, which is where your base is. One of 3 possible results can occur:

1. The weight line does not touch the base - Your character will fall over.
2. The weight line is near the edge of the base - Your character is still technically upright, but is on the edge of falling over.
3. The weight line is near the middle of the base - Your character is balanced and upright, which their weight equally distributed.

This isn't just true of people, though. These rules apply to any object (with the base covering all points of it which are touching the floor).

This can be further complicated by the presence of "unbalancing factors". For example, a character carrying a large sword will have a different centre of mass to someone not carrying said sword, because sword adds weight to one side, shifting the centre of mass towards it.

If you want to really understand what a centre of mass is and how it works, I recommend studying rotational moments.
