This is my 3rd Blender finished/rendered art work. I must say, I am pretty happy with it!
I saw this in a youtube tutorial, anyway, Good work, keep it up!
It could use a better sense of scale (lots of small pieces, more detail in the edges, smaller details in the textures ect…).
Right now the planet looks somewhat small (in my perspective based on the detail), it really depends on whether the size is supposed to be more like Ceres or Vesta than Earth.
