Custom Modpack loads then crashes

[Savidge]

Hey there!

I was wondering if anyone here could help me out.
I recently decided to compile my own Modpack, and I've followed all the instructions as best I can.

Everything seems okay, but when I hit "Play" in the launcher, it runs through all the file verification and then just doesn't open. I've tried a large number of things trying to fix this.

Could someone please take a look for me and see if you can help? It would be greatly appreciated.

Here's a link to the pack:

If you could help, that would be awesome.
