The briqhtness on the render isn't very qood and the sides of the backqround don't look qood either, the text doesn't fit try placinq it somewhere else and make it smaller, the render needs some better work mate try some tutorials and stay practicinq.

I think it's too brightness on the bg. Background at left and right is too dark. Try to make a background between brightness and dark with a good result. Text needs more lightings and work. KIU

the sides looks too dark
text is nice, render effects too
but the middle of the sign looks to bright
keep praticing and improve your lighting
stay active
