I have a 5 year degree of Architecture from Tuskegee University. I have been practicing in the field now for a little over three years. What other areas can I take my career? (i.e - fashion, automobile design)
Your own imagination is your own limit. The following portion of the ARCHCareers.org website has a beginning list for you to consider.
Basically, think about the skills within architecture that you enjoy that could translate to another career field. Recognize that some new disciplines may require additional education or training.
Also, think about why you are wishing to explore other career fields. Is it because of the discipline of architecture or your employer. Sometimes, it is the work environment not the discipline.
