sweep

Hi!!! I'm new to this software. And I'm finding some setbacks to solve this question. I've made relations that it needed and I tried to sweep. But I always end up like that (please, see the image added), with a beak on my drawing. This drawing should looks like a mouse, but it is a bit far from it. Can anyone help me, please??? I know that I'm doing something wrong, I just don't know what it is. Thanks in advance! Bye!!
