How important is 3D/360° drawing for mobile creatives?

We built Procreate+ Studio to offer a free 2D canvas with brushes and layers, plus a unique 3D/360° sphere view that works across Android, Windows, and web. Most apps either ignore 3D or lock basic tools behind expensive paywalls.

We want to know: does the 3D feature actually matter to you, or do you mainly stick to 2D? Also, what's your take on keeping core tools free while unlocking premium features (AI Assistant, 3D recording) via a $5.99/month subscription?

Looking forward to your honest feedback!
