Analysing Logo Designs

I have analysed four charity logo's similar to the charity subject i am going to have, becasue this will help me to establish what makes and effective logo.

Above is my analysis of Thames Valley, overall, i feel it is not an effective logo as it is too simple.

Above is my analysis of the 'Freal Cat project' charity, the logo is fairly effective but could still be improved by having a cute cat and less/smaller text.

Above is my analysis of the cats protection charity, the colours are effective and overall the logo is very good.

Above is my analysis of Catchat charity, the logo is effective because it shows the company name and website address and is also very simple with one colour used.
