Genesis - Lamb Lies Down On Broadway Bass

This is my first tab so I guess rate it? I dunno. Anyways I noticed there were no bass 
tabs for this song and it's really awesome on bass, so here's what I think it is.

I suggest using a pick, because that's more what it sounds like.

Tuning: D# G# C# F# (1/2 step down from Standard)
