The photo is quite blurry, but at least we can see that the boots have flat heels.
The sculpt looks pretty well done, with a believable very muscular shape and good proportions. She reminds me of a firefighter I knew a long time ago.
Let me think aloud about the size of the sword's owner. A Roman gladius, which appears to be the inspiration for this sword, was 24-33 inches, and the average height of a Roman soldier was 5'7" or 67 inches -- both figures from a quick Google search, so they must be correct!
If the guardian is 72 inches tall -- let's assume that she's a tall barbarian -- so is the sword. That is, about 3 times its length for a Roman soldier. So the owner of the sword should be 3 x 67 = 201 inches, or 16'9".
That's a ball park figure. Other variations -- shorter guardian, longer gladius -- are left as exercises for the reader.
