Hi, Peshang. I'm new here too.
I assume your digital art is drawing and painting. What software are you using? Do you have traditional training as well, and are transitioning to digital?
Is your sculpture real-world, or digital? What medium do you use (real world) or what software (digital)?
I'm traditionally trained, and have been "transitioning to digital" for the last ten years (yeah... really). I'm even now doing a massive comparison of software, for example, to see what works for me, and what doesn't, so I'd be interested in any input you've got on how different software packages are working for you.
See you around.
