your stuck in boot loop .. possible reasons is 1. the no of partitions on ur SD card[it was the issue with me atleast]. i dont know how u have partitioned your card but ideally format your card create a ext4 partition of around 1gb keep the rest a fat32. copy the rom and gapps provided in ur fat32 partition. reboot into recovery , wipe dalvik cache n factory settings n install the rom n reboot . hopefully it should work.
another source of problems is your recovery . if problems persist update your recovery to the latest version TWRP 2.6.3 is good enough n then try again.
hope it helps
