Runner, please consider replacing the second pair of 1u Ctrl and Alt keys, which aren't commonly used, with the far more useful R3 PgUp and R4 PgDn keys needed by 65%/75% users. In fact, two 1u Ctrl keys aren't used by any modern layouts outside of 40% boards, and two 1u Alts are only useful if there are two 1.5u Code keys as well, which there aren't in this set.
As it stands, the set is missing a R4 1.25u Fn key, which a lot of people need for 60%, 65%, 75%, TKL etc. boards. Consider changing Menu, a less frequently used key, to Fn. This shouldn't be an issue, as Fn is a versatile legend that can also work as a menu key, whereas the opposite isn't really the case. In fact, this is exactly what most sets do: they include Fn in their base kits instead of Menu.
Finally, since your set is using single-line Scroll and Num keys, please consider replacing the stepped Caps↲Lock legend with Caps, for a consistent single-line look across the board.
Based on previous experience with GMK, none of the above changes should affect existing quotes, as they are legend-only changes. If you still haven't received final quotes, though, you may want to consider dropping the numpad 00 and some of the extra ISO keys to help keep the cost of the base kit down.
