I love the hop selection. Seems like most recipes are for American versions, but I am a fan of a more traditional Brit version. I might only suggest two changes. You could add 50% to both the roasted barley and chocolate malt. Also, for fullness I would get rid of the lactose and get that from a grain such as Munich or Melanoidan instead.
