Awesome work, congrats. Yeap, readibility is a little hard in small numbers (red over black doesnt help) and the upper gauge. And just a tip, you are persuing original designs so you don’t need direct references to market brands, grow your own brand and that way you go to avoid rights issues. Welcome to the community!
It looks good however in my Audi the fuel gauge is located on the right hand side of the dashboard
And I would have no issues reading red on black - i like it.
Edit:
I installed this face and now I know what carlosfilippa meant. These red numbers are simply too small…
