Hello, Jonathan. Here are a few examples of my work, https://www.artstation.com/alvordr. In the past, I've focused on organic modeling, but more recently have been mainly concentrating hard-surface modeling since I also do 3D printing. Feel free to DM me here if you want to collaborate.
I'm not familiar with TB but, coldn't it be the 'channel' slot which is marking the 'R' channel instead of 'RGB'? Plus: I think your 'roughness' map is actually 'glossiness'.
Transform Toolbox Awesomeness Pressing 'R' will Reset Xform and Collapse the Stack: Pressing 'Origin' will move the pivot to 0,0,0 Precision rotates there are quite nice as well. :D
