Ryo, very nice work. Could you try putting the solid black bison in #72 (I have the rights to this, and have used it before). I'd like to see how it fits in with the design and background you've created (it's the one in the all black example I've provided, with the Flint Hills Studio written over the bison. Please keep bison all black.)
Lastly, might you try having Flint Hills Studio smaller, one one line, centered between left and right of logo, with same Western style font you used (and Studio in black, too)?
Thanks!
Jon
