>>1695250You need to set an artboard for the image and export with page so you don't get the extra lines that you drew outside of the artboard at the top and bottom.
There are two ways you can do this. If the original is not a wallpaper, you just select the Model image, press Ctrl+Shift+D, Click the "Resize page to content" addition, and then click "Resize page to drawing or selection". If it is a wallpaper, you will have to manually set the margins for just the character and click the resize button.
