Hi,
Firstly does this score give you the points you need to make your total 67 points? Secondly your proffession is Accountant which is not like 4131 ( Lecturers ) who need good ielts score because of there proffession. Normally CIC does not have any minimum requirement for english its just that we have seen some applicants with low score were asked to proove there english proficiency again, so it really depends on the visa officer if he thinks its good enough then it is. But normally i think you can improve your score and if you have time then re-sit again to get a better score.
Cheers
