looks professional and fun. the guitar and the pandeiro detached are fun, I don't know what are those 3 cactuses, but they look colorful and ok.
the only thing I thought it's a little bit strange is the brown-beige combination used in the name. Aren't they too serious for a carnaval party?
but the overall design is really beautiful, it's even good as it is, IMO

Main type can be slightly bigger, instruments can be smaller. Tough read on the "L" in CARNAVAL. Move flourishes further to the right. Take out all black elements. I agree with comment above, I wouldn't use brown for a theme like this.
