Answer:
No, it's not ma bro. In this your sentence it's gonna depend on what you are trying to say man because that sentence translates as "I don't like really your yellow jacket"
So if you were trying to say "I don't really like your jacket", it should be "Je n'aime pas beaucoup ta Veste Jaune"
But if you're trying to say that "I really like your jacket", then it should be "j'aime beaucoup ta Veste Jaune.
