Alfa the text and the cloud feel like 2 seperate things. Need something to help them flow together

Bravo Try making the letters offset at different angles (very subtly), and lower some into the cloud to make them look a bit more 'floaty' and relaxed. Try a slightly thinner/less round font?

Charlie If rounded font, why edges on the cloud? These two domt seem to work together. I like the idea still!

Delta Agree with the points above - especially offsetting the letters into the clouds!

Echo looks like a Skype knock-off

Foxtrot A little TBS in there as well
