I would do this to make it look even better:
Make one of the moons bigger than the other.
Maybe it would look better if the text is on a planet?
Add some meteors to it.
I think this is a great improvement to the sword logo I’ve seen earlier. This logo is able to show the theme of the text and the black background contrasts with the text wonderfully. Although I do have a few things to say regarding improvement if you don’t mind.
A few things you should improve on: I personally think that the outline around the text (the one after the black outline) should be either white or brighter colour to help make the text ‘pop out’ more, I think the same colour outline for text kind of defeats the purpose of an outline in the first place but this is just my opinion.
I really adore the background as well, however, I would put some more effort in to make it have a racing element to it. I have a couple of ideas such as including a rocket, adding a stripe pattern or maybe including something that relates to racing such as speed - including either a shooting star or moving asteroid as these are usually known for being fast. (hope this makes sense lol)
These are just some ideas but I encourage you to not be afraid to start being more creative and experimental with your logos
