This was a really difficult one to make, especially since I've only used the main brush of the art software until now. Anything I could have done better so I could maybe revisit when my skill level becomes actually good? I don't really know how to do shading on metallic surfaces. Any other critique is welcome as well! Second picture is source!

2001 Space Odyssey art study, shading this one was extremely difficult. I hope that it stays up on here because I tried my absolute hardest on this one.
