Lights Added to Existing Circuit Don't Work?

I just installed two lights in my bedroom closets. I disconnected the room's overhead light switch and connected the wires to route power up to the attic. I then cut into the wires that were going to the overhead light and installed a junction box in the attic. I ran a 12-3 cable back down to the wall switch that controls the bedroom's overhead light and connected the black and red to the switch. In the junction box I then connected the 12-3's black wire to the black, bringing power up to the attic. I then connected the red to the black that continued on to the overhead light.

I then connected the neutral that came up from the basement to the neutral that goes to the overhead light. I also tied in a 12-2 cable to the junction box and ran power to the two lights I installed in the closets. I did this by connecting the wires to hot and neutral lines that I brought up to the attic by re-routing at the wall switch. In the junction box I've got the hot wire connected to the overhead light and the wire running to the added lights.

Once I had everything connected, I turned the power back on and I am getting power running to every point, but the lights don't turn on.

What did I mess up?
