Nice clear photo from which you can clearly identify the subspecies. Have a look at www.avibirds.com/pdf/A/Aalscholver1.pdf and have a go at a revised ID, someone else will if you don’t :-)
... for the article which is a little deep, my aim was to point you towards the diagram only – though the rest is interesting if you’re that way inclined - and I do think you have it right.
Can you clear up something for me please. Is there just an ordinary Great Cormorant or are there just two sub-species S.p siensis and S.p carbo. Or are there 3 in total ?

According to the BTO there are 7 subspecies of cormorant worldwide (http://blx1.bto.org/birdfacts/results/bob720.htm) however P. c. carbo and P. c. sinensis are the only two found in the UK.
To answer your question specifically there is no Great Cormorant, they are all one or the other subspecies. P. c. carbo is the nominate subspecies, that is the first to be described – the reference subspecies if you like.
Hope that helps
It does thanks, you learn something new every day.
