请大伙帮帮忙改进或修改下列英语文章 这是即将参加一个英语比赛的自我介绍 要比赛了

Nice to meet you all.
I am a twelve years old and as you can see, I'm a sunny and exoscopic girl.[exoscopic 外向的]
[My disposition is extroversion, the interpersonal relationship is very good!]这句话很不地道,不建议说.
I have a lot of friends and I get along with them well. [get along (with) 相处融洽；词组,地道.]
My favorite color is green, for its meaning is hope. [变换一下句式,不要老是I like .]
Also I like listening to music. Music can always nourish people's heart.[音乐可以滋养人们的心灵]
Today, I am very glad[比happy好] and exciting to be here, to participate in[缺少了介词,语法错误] the [缺少了the]‘star of outlook’English Talent Competition.
[And I belive that I will try all my best to demonstrate!]中式英语,建议使用如下句子.
And I believe that I can behave well and show you the best of myself.[我相信我能表现出最好的自己]
[I hope i can pass the exam.]不建议说,很别扭.
可以说 I hope you like me and give me a chance.
Thank you very much.That's all. Hope to meet you again.[希望再次见到你们.]
