My friend,
When I instruct a fighting school, my brothers and I make it a point to observe each person's individual characteristics. Not all techniques work the same for all people, but there are many advantages to each individual. Learning what works for you or not, is of course up to you, however you must find an instructor who is used to your type, and capable of supplying plenty of options. Without writing a book, let me assure you that you have great strength in being close to the ground and anyone who would underestimate this individual could be in very big trouble.
There are so many things that come to mind but really it is more appropriate to see you move instead of how tall you are. I am sorry but words are not enough to pass on to you what I would recommend. I would have to see you, in order to properly assess the best techniques for you.
