Thank you for the advice. It is much appreciated!

Hi everyone! New to the forum, very beginner photographer. Took classes in college, have done shoots for family and friends. My passion is photographing people/animal portraits. I am planning on buying the Nikon D5100 that comes with a standard 18-55 mm lens. What else can I buy that would help me capture AMAZING portrait shots? 55-200 lens? 70-300? Wide angle or Macro? Please Help!!!
Suggestions, tips, opinions on this particular camera welcome!
Thanks a bunch!
