On the subjective matters: IMHO the two tones of green go well together; the orange clashes (in the jacket itself, the orange is placed upon the insides entirely and does not interact, so to speak, with the outer greens).
As per layout:
- Atlantis ISO — go full English (USA) or full English (UK), or both, but avoid the Atlantis ISO mistake.
- No numpad? If you choose not to include it, say so (and why).
- No split space bars? (as above)
- I dig that you have Super and Alt both in 1.5U and 1.0U. That said, no 1.0U Ctrl keys?
