Often blue and red sets don't work well given it's polarising contrast against each other, but I think the combination of different hues and cream alphas really transcend the set for me.
Some minor changes might be to use the stock L9 colour for cream alphas as it looks almost identical to your render and would reduce the variance of colour matching. Also, if you're offering stepped Caps Lock, I'd suggest keeping it traditional text instead of Icon with the other mods and having it mod-coloured instead of alpha-coloured (and moving it above one row from what it is currently to make it clear it's R3 and not R4). Accent Enter Numpad should be in place of the alpha-coloured one but I'm sure they're just minor errors to the kitting (some R4 mod texts are weirdly aligned).
Hope it works out, and look forward to seeing updates soon!
