I wonder if you could get rid of the PSI thing for Lamar and Miriam, since they don't use it from the looks of things. It's kinda awkward having it there. You might be able to show off something else instead? Also, something about how HP and PSI doesn't left-align bothers me a bit. I know the gauges are taking up the room on the right side of the words, but even just adding a little spacing should help.
I'm picky. >.<;
Sorry.
Otherwise, I really like it! I'm partial to larger text in menus and it's very easy to read. Sometimes simple is best.
