My First Board - Was this a good choice?..

Hi!
I have just bought myself a 7'6" Mini Mal NSP Surf-Betty, upon someones recommendation, but I'm a little 'confoodled' by all the conflicting advice out there on the correct size of beginner board. I'm 5'8" and weigh approx 9 stone, and the water I'm going to be in at home are UK North East and South West... Was my choice of board a little long? Would a 7'2" been a better option, or will the extra 4 inches prove helpful when I'm learning?
Cheers,
Beth
