Hez the man!
Getting tighter on the sculpt. The overall form looking good. Time to add the hammered metal bumps and
check the symmetry vertically and horizontally and also flip it upside down and you will see anything not symmetrical/ unbalanced
If you have a mirror u can look at it and you will also see irregularities...Not that I see anything wrong here.
Will u be using real parts for the Tube on the side temple and other round rivets stuff? It will help achieve a more realistic feel to it
Don't worry its not "cheating."
Good work dude keep it up!
