Default RE: 60

You may want to look into one other change. The horizontal stab seems a hair small for the duty it's performing. Run the design through one of the online CG location calculators and see if the tail area and boom length is sufficient to support the CG at the location you've shown with roughly a 5 to 7% stability margin. I think you may find that you need to enlarge it by about 15 to 20% in area to achieve this. But that's just an eyeball guess without the location calculation to support this.

LInks to CG calculators is found in the sticky thread at the top of the Aerodynamics forum.
