D_Houdini

Hi, I need help with creating a tornado in Houdini. I'm using houdini 16.5 I have all the necessary elements to create a tornado ( Particles, Density and velocity ). But I can't seems to make it look more detailed. Tried to adjust the velocity, turbulence, noise, swirling, it still look plain. I have attached scene file in here. Tornado_1 is the current tornado I have. Tornado ref is the kind of detail I'm trying to achieve. Thank you! please help! Tornado.hip
