Research paper for Cloud Storage Forensics

Hello
I am doing Capstone project for my Master's degree on the above mentioned subject. So far I have come up with following ideas
1)Regshot for analysis of Windows Registry changes.
2)Process Explorer to explore the windows processes during and after accessing cloud service.
3)Analyze Cache, Cookies and History of web Browser.
4)Analyze Prefetch Files.
5)Windows File Analyzer to analyze Shortcut or .lnk files.
The research is in initial stage and I understand that the above mentioned venues might not produce valuable results.
I will be grateful if the members of this forum can provide some directions which might help me in the research.

Thanks
