Chaltab: Stereotypical, but not a bad approximation of an old English gent. This breed is rare nowadays, but can still be found among politicians and rich folk. The true test of an accent is weather or not the user would blend in to the desired country. In Chaltab's case, I suspect not, but 3 out of 5. Good effort.
Ric: Minus points for using bloody twice in the same sentence, which is just lazy (saying bloody may help your English accent skills, but saying it repeatedly makes you sound like someone who is trying to sound English but clearly isn't). Whereas Chalts went for the posh upper crust fox hunting English, Ric has gone for the salt of the Earth football fan (or hooligan) London Accent. I suspect Ric has seen Lock, Stock and two smoking barrels or Snatch once too often or is basing his English Accent on Michael Caine. Although it's not a word I personally use, starting the sentence with Blimey was a nice touch, so Ric also gets 3 out of 5.
Incidently, my accent closer to Ric's attempt than Chalts. I suppose to an American or in Ric's case a Brazilian, the closest example I can think of is a slightly more articulate version of the the guys from Spinal Tap!
