Split Level Hip Roof Plan Help

I'm hoping someone here can help me out with this. I can't seem to figure out the rooflines for this dropped addition. Specifically, I can't seem to determine the layout on the roof plan.

There will be a large room added along with a smaller mudroom off the side. The addition is dropped +/- 8" so the overhangs will come in lower than on the existing. All pitches are 4/12. I'm not sure if I'll need a saddle to ensure good drainage.

I've uploaded a pic showing the elevations and a layout of the existing roof. http://imgur.com/QBBukIt

I've literally spent hours drawing and reworking the linework only to come full circle. I'll be the first to admit I'm not great at rooflines!

Thank you!

This is what I understand it to look like. http://i.imgur.com/4uDVvOK.jpg

Thanks for trying but this isn't correct. The new roof connects with the existing hip rather than into the wall below. There will be a hip at the mudroom roof too, and all hips are at 45 degrees since all pitches are equal.
