这句英语【语法】有错吗?Indicated above is a picture that vividly portra

Indicated above is a picture that vividly portrays a large kite,flying happily in the blue sky,connected by a long string .
这句话属于一个高级句式,用了倒装句,还有两个非谓语动词形式,我觉得如果在connected前加一个and 更完美了.
改为being connected不合适,因为现在分词的被动式表示动作正在进行,意思是connect的动作正在进行,还没有连接好,而过去分词既表被动又表完成.

1 正确
2 你的改法没问题。前者只是省略了being

最好是
picture indicated above is a vividly portrays with a large kite, flying happily in the blue sky, connected by a long string.
下面你的改法没错。
