Great start looks like you have general knowledge about proportion but you are just a fine hair off on a lot of things. I strong recommend working with a reference image and taking a good hard look at landmarks on the body.
A good general rule to follow is the heads rule, basically measuring and sizing the body off of the size of the head. Most artists will recommending using 8 heads and I do as well, it's a good solid even # and that tends to work well with pixel art for some reason

(might have something to do with working on a grid :3 )
Things to notice!
First notice the character is one pixel taller than 8 heads, this is due to exaggeration of the hair up top.
Now starting from Head numbero uno which is at the top!
Head one: Is the head.Head two and three:Neck, shoulders, and end of rip cage (1/2 of stomach as well, pixel art is weird at this resolution)Head four:Here lies the other half of the stomach and also your hips and very top of crotch.Head five and six:At the top of head five is where the crotch ends and thighs begin all the way down to the kneesHead 7 and 8:Pretty easy your calves and your feetSuch ends our adventure down the female body. Hope this helps.
