哈哈,对不起我还是认为你之前的logo好看"如何英语表示呢?"

你那样是不对的，你完全只是中文词语翻译成英文单词进行的嵌套。
I'm sorry to tell you that i think your former logo is much better!

但是你如果要用你自己的表达的话，可以把你的句子改成：
I'sorry,but i think the logo you used before is more beautiful.

I am sorry. But I still think that your original logo is better.

Haha, sorry, I still think your previous logo looks better.

I am afraid that I think the last logo is better.

I am sorry. However I still think that your original logo is better.
