After most people, myself included, have some success with the handstand they want to move on to a variety of stunts, most of which are much harder.
My advice, nowadays, is to stick with the handstand itself for a bit longer.
Yes, you can always just work on adding more time in a hold while improving your balance. But to spice it up a little bit try changing up your position.
There are a huge amount of different ways you can do this with different areas of your body. For today let’s focus on the legs.
Again, any possible way you can move your legs can be done in the handstand but let’s narrow it down to just one. The Scissors Handstand.
“Do a hand stand in nice form, then separate the legs, one backward and the other forward. Start the legs backward and forward in scissor fashion. Go slowly at first, and increase the speed, and come to a sudden stop with the feet and legs in nice form. While in the motion, the legs should be kept straight, with the toes pointed. This trick is very effective and is not hard to learn. Variations of the above are, scissors while walking on the hands, also scissors with the head forward through the arms.”

Good Luck and Good Hand Balancing,
