Is it rude to ask your tattoo artist for a specific kind of shading.? Black n grey

du

My artist is great. Im getting flowers. She seems to mostly do whip shading in her flower tattoos. But i dont like whip shading so I wanna ask her to do another kind of shading. It's black n grey so I feel the shading matters more.

This is whip shading

This is the shading I want
