The attachment shows the uninstall was successful on the database engine. It failed on the Data tool, integration services, and Data Quality Client. Do you have these items installed on your server? what does SELECT @@version return?
All three of the failing uninstalls are shared features so there is connection there but i am unsure why the uninstall is failing. You can look at the setup log for more info. should be at C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\Log\summary.txt
