Hi John,
I have a suggestion on Your Patch design and - obviously - It is something very personal, so You are free to not consider it at all...
I worked a little bit on Your image (I hope that this thing does not offend You...) and I enlarged a little bit the Sand/Dewback figure, moved the twin suns to the right and shifted a little bit the vaporators (and the two on the far right are also scaled-up a little bit).
I was just trying to highlight more the Sand/Dewback that - for me - was a little bit small.
Let me know if You like it.
Cheers,
Alberto
