Opinions on this as a Typical British Bitter recipe

[BarryNL]

I want to try and brew something in the area of a Young's Special (or even a pint of mixed). I found the following recipe (for 19 litres/33 pints):

2kg English light dried malt extract (= 4.5lbs)
340g crystal malt (= 12oz)
14g Fuggles (boil) (= 1/2 oz)
21g Goldings (boil) (= 3/4 oz)
7g Fuggles (flavour) (= 1/4 oz)
21g Goldings (flavour) (= 3/4 oz)
14g Goldings (aroma) (= 1/2 oz)
English style ale yeast

Glucose for bottling
Expected o.g. 1.042, f.g. 1.010

I'd thought of maybe giving this a bit of extra character and increasing the o.g. by also adding 500g of amber malt extract and upping the cara-crystal to 500g. I'd use Wyeast 1098 British Ale yeast. Also, only generic (probably Dutch/German) light malt extract is available here - I don't know if 'English' tends to be in any way different.

What do you think? This is my first attempt at doing anything other than a kit so I'm not really sure what to expect.
