I can paint concept art, though Ideally, I am a character concept artist, and I can also do environments and backgrounds, my main software of use is Clip Studio Paint for 2D, and I create rough concept models on Blender and 3DsMAX.
though I am a concept artist by profession, I have been illustrating for over half my life and still much prefer it.
in addition, I have been 3D modeling for over 2 years now
