Sand art

Some people do beautiful art like this, and I'm here trying to figure out how to draw a stick figure.

I can pile sand in my shirt and walk around with my sand baby.. You could say I'm pro

Then some guy comes over with a water bottle and trips...

How do people even do this I mean last time I went to the beach I made a mound that looked so bad I had to intentionally destroy it.

How can you even do that????!? I struggle making sand castles
