Entry #9 is quite good, can we get an example of it without the word Engine at the end and one with the icon to the left, some other variants would be cool too. Entry #10 is too dark, but again, like the styling.
Can you see if you can adjust the font to something closer to #34. Also please change the font underneath back to black and add the 2x lines as in #34 to either side for effect... Thanks!
