The lowland plain (slightly bluish in this image) is the Fylde, with Blackpool Tower visible on the coast.

I've frequently seen Liverpool from here, and occasionally been able to distinguish the Welsh hills, but it's rare to see the latter so clearly as today. Mouseover for an enhanced version of the image, which reveals a profile I find very familiar, as I grew up there!
The highest, central peak is Moel Famau (554 m). There's a Jubilee Tower there too, which I've tended to visit at midnight to see in most New Years since my teens.
To the left, the Clwydian Hills head inland towards Wrecsam and Llangollen; one of the peaks is Rhiwabon (Ruabon) Mountain. I'm afraid I can't identify the peak furthest away, at the extreme left.
To the right of Moel Famau, the ridge ends at the coast, at Prestatyn.
