Nice to see that you kept at it, you worked hard, and I'm very happy that it paid off for you, dude.
I think you have a shot if you were to reapply at the schools that you mentioned above. You have real concrete improvement, and this will look good.
In addition, have a look at Said, Judge, Manchester Warwick (UK), ISB, IIM (but you know that!
), Johnson, Kellogg and Babson in the US, Nanyang and NUS in Singapore. And if you are open to European schools not in the UK you have a bunch more good options.
