That finish is not bad at all for steel, especially for a new operator. I wish our new student machinists would feed that consistently!
Have you ever considered investing in a few carbide endmills, like 1/2" and 1/4", for use on steel? I have found that using a 1/2" carbide for steel greatly improves the finish due to the ~4x rpm that I use compared to HSS.
That and a face mill. I can't get enough of that 2000rpm carbide insert face mill finish!
Also, why have you put the part so high in the vise/ stick so much up?
