You've changed the set's profile/manufacturer and updated the kit renders, but you haven't addressed any of the issues present in the kits (most notably the alpha-colored “accent” keys).
Speaking of which, there's one additional issue in the new base kit: the R3 '@, #~ keys you added don't fit in since there's no ISO-UK support. They should either be removed, leaving only R3 \|, R4 <> like in the previous iteration (I recommend this approach); or they should be supplemented with the remaining ISO-UK keys (in which case R3 \|, R4 <> should be removed). Having only two out of the six ISO-UK keys and mixing them with terminal ISO doesn't make sense.
