Xara :: Create Exact Raven Image

I can create the exact Raven image I want from a photograph he found.However, no matter how I try to fill in the silhouette, no matter what commands I attempt (such as convert to shape), all that happens when I attempt to set fill color as black is that the line changes color. It's as if the line itself is the shape, if that makes sense.

By the way, I originally traced it with a series of lines and then joined them, as I couldn't do this with one continuous line.

I tried converting to shape and then combining and intersecting, subtracting, you name it, using a black shape behind the lines, hoping to get a black Raven image. But to no avail. What do I need to do to fix this? I'm thinking if I retrace it again, I'll likely make the same mistake(s). I searched for a solution in this forum, but "fill" gets a ton of results.
