Not bad but nearly a mess.

To cast this I ran the crucible quite full. With the last aluminium ingot floating in the melt, it was about 8 mm to the top. Of course as this melted, and the rest of the melt got hotter, the crucible ended up pretty much brim full - stuff expands when you heat it up - who knew?. That makes for a touchy time pouring it. Spilling liquid aluminium is probably a bad way to end the evening.

Here is the pattern with the casting, I've cut off the feed gate, and filed down the flashing around the edge.
Here is a closer shot. For a sand casting the finish is pretty good.
