Sounds ok, I would back down the crystal malt, though, but that's a personal preference thing. If you don't I think you should mash a bit lower, like 150ish or it'll be a bit too sweet for the bitterness (assuming you're going for an ESB) IMO. When I punched the numbers it looks like 1.049 OG and 38.1 IBU. With the 154 mash temp it'll have a full body to it, which is why I'd choose to decrease the crystal to about 3/4 or 1/2 lb. Also, that last hop addition isn't "to style" but I likey...
These are just my thoughts, though, either way it looks like a solid ESB recipe to me.
