^ ukhti, I really can't decide if its haram or not. Maybe someone more knowledgeable can tell you, but there's one thing: that the person who drew this, really liked their art work, so they hung it up, admired it, other people admired it, and soon, next time, would the person decide to draw the full body? Trust me, I know drawing can be addicting. You draw a simple face one day, next time, you draw it more detailed, and then soon, you're saving up your drawings carefully, hanging them up, framing them, and before you know it it's become a habit and you start drawing in your spare time, more and more detailed.
There was an image maker in the Prophet's (SAW) time, who asked about this. And the Prophet (SAW) said "Every image maker will be in the fire." The image maker got scared, and asked that this is what he did for a profession, so what could he do? And Rasulallah (SAW) answered that if he must draw, then to draw inanimate things, such as rocks or trees, or water or nature or anything that 'doesn't have a soul.' So anything, except animals, insects, birds or people is allowed.
Also, Aishah (radhiallah taala anhu) once had hung up some curtains with pictures of animate objects in her room, and Rasulallah (SAW) came in and told her to remove the curtains and that "The angels of mercy do not enter a house where there is a dog or a picture, and that the person who made those pictures would be in the fire."
Therefore, ukhti, I'd refrain from drawing animate objects, especially if its just for fun and enjoyment. If its made to teach or instruct children, or as a children's storybook illustration, or a toy, then its okay to an extent.
