That pattern is tough to read, thin your paint with gear oil and take another pattern, make sure to put plenty of drag on the ring gear while you turn the pinion.
It seems pretty close to the Pirate guide. They say this is the correct pattern:
jam a wooden block in between the ring gear and the housing to give a lot of resistance to turning. And as Chris mentioned, thin it out a bit. Be sure to wipe off any old paint, before trying a new pattern.

Pinions too deep.... Drivable, but not right.
you do need to thin out the paint some. Just put some oil in it not a ton just a bit. It will make the paint smear off better.
It certainly looks like its too deep. Look for sharp edges, they are bad. It appears you have a sharp line on the bottom.
But once again, you need to thin the paint a bit.

What are your settings now, and did you use some sort of resistance to get that pattern?
Didn't change anything just added resistance

too deep looks like.i cant see the second pattern but doesnt look like the gears are meshing correctly.coast side looks ok but the drive is off.its gonna heat up real quick that way.i had mine like that and overheated the axle.i went a few miles and the diff was smoking.lol.ha dto back it off a bit.looks to need pinion closer and shift from left to right side.id start with .002 and see what you get for a pattern.its been a while since i did one but hopefully someone will chime in if im wrong.
I found my problem with the pattern. I was only snugging the carrier bolts, not torquing them. Once I did my backlash got real sloppy so I added more shims to bring it back to spec. Now it sits at a perfect .008" and the drive pattern now sits slightly more centered. I figured it wasn't off enough to justify another trip to the machine shop and risk them ruining the bearing when pressing it off. Unfortunately I got too excited to put it all back together so I forgot to take a pic. 
Oh well, thanks for the help guys.

Glad you figured it out. Sometimes if you're lucky it's something as simple as torquing everything down.
