Judging from the screenshots the rom appears to be using the modded S4-alike launcher which isn't even close to the TW launcher found on the S4. It's worth noting that several UI elements in that ROM are S3-based, likely yet another ported S3 CM11 theme. The real launcher wouldn't have the bugged home icons on the homescreen.
P.S. You should credit the dev who created that S4 launcher mod.
He is already included the credits for my S4 Pack, you can check my signature ...
