Hmm...not easy to tell from the pictures.
Here's something that may help though. If you can't find the leak any other way, get some of this UV sensitive leak detection dye and this UV light kit. Clean everything thoroughly, add the dye to the oil, start the engine, and then look around with the UV light using the glasses provided. You may be able to see where it is flowing from more easily that way. This works well on ship engines where it is difficult to move around and find the exact leak source.
