A few quick comments:
1a) Please note the alpha key acompanying the vertical ("ISO") Enter key is incorrect and does not support a proper English (USA) over ANSISO or ISO keyboard layout. You have an R3 #~ key instead of the technically correct R3 \| key (the R4 \| key is fine and can remain as is, OR can be changed to an R4 <> to follow the terminal style instead of the PC style).
1b) It can be either the above AND/OR complete support for English (UK) over ISO, meaning the missing keys R3 '@, R1 `¬¦, R1 2", R1 3£, R1 4$€ and AltGr (in each relevant size) should be added. The best option of all would be to have full English (USA) + English (UK) support (and that would mean exactly one more key than full English (UK) over ISO support).
2) I'm not a fan of the Dixie logo on a non-Dixie set.
3) I'd add an option for burgundy split space bars.
