Use the CLEO method to structure your answers if you think its your writing style - I did this at Uni to get my law degree, found it in an excellent book on writing legal essays.
C - claim. Set out what the particular issue is relating to the facts
L - law. Set out the law relevant to the issue
E - evaluate. Apply the law to the claim/facts
O - outcome. Summarise and conclude.
This can be applied at paragraph level for multiple issues with a larger conclusion at the end, or as a whole in the essay.
