Part of the reason that flag looks weird is because you're using a pure 255.0.0 red, which no (respectable) Communist country really did:
Union of Soviet Socialist Republics: 204.0.0
People's Republic of China: 222.41.16
Socialist Republic of Vietnam: 218.37.29
Democratic People's Republic of North Korea: 237.28.39
Socialist People's Republic of Albania: 206.17.38
The font looks too cheery because you're using lower-case. The "E" should be small-caps and the rest in all-caps. I'm not sure what font that is, but something that's far closer to the original Brazilian flag would be Helvetica or Helvetica Neue, in bold.
