As a tube wrangler myself, it bothers me to see unnecessary bends. I realize there is no fluid flow in the square 'tubes', but, I don't like the arms on 'Grampa Jay's' FEL; or at least the drop down on the boom arms near the post. I think it would be more appealing if he followed the curve of the hood. The rest is okay, and I like the sweep back at the post to boom hinge.
I hope your not planning to paint green and yellow.
