Some suggestions for improvement :
- The text could have a shadow and/or a neon-like outline.
- The roadless floor (and even maybe the sky) could have "perspective vertical" lines too, like the road.
- The moon (?) could have a similar neon-like outline.
Vaporwave images usually have brighter, more striking colors, adding some brigh pink/blue highlights to the purple would really do it good, I'm sure.
