Present Perfect Continuous - correction?

Hello,

Could somebody possibly correct any mistakes in the following passage, please? I think the present perfect continuous in the last sentence is ok, but I somehow feel there may be something rotten in the state of the text. Any comments or advice are welcome! Thank you in advance!
