I am no expert but I know she is NOT persian Since I have what I am pretty sure is a Maine Coon mix myself and have read a bit on the breed - I do see some MC characteristics in Angel - like the broad muzzle, huge paws, tufted ears and the rounded eyes. She also appears to have a mix of long and short hair and something of a "ruff" around her neck area. MC's will have a type of hair that does not easily tangle - my Dylan has never even had a mat! The fur on their back is shorter and they tend to have very long and thick tails. Tabbiy color is common but they come in any color.
You will get better answers I am sure - but I do see some MC in her No Persian though!!
