Hi - I like all of your designs! In general, I'd like to emphasize on KIteBar and make the "the" smaller and unobtrusive. Also, I'm not so sure about the steam on the coffee cup, creates sense of cold weather/warm drink, and it's exactly the opposite there.
#23 - I like the orange sand bar and the simplicity of it. Maybe too simple? Can you try adding one more color, add a coffee bean maybe as the dot of the "i", and maybe make the palm tree look a bit more like a palm tree, maybe by just adding one more leaf or make the trunk look like a tree trunk.
#19 - not sure what the third icon is.. looks like a space ship to me :). also, see the general comments above.
#21 - great idea! See general comments above. Maybe replace the coffee cup with a coffee bean? Also, I'd rather not have the word "bar" stand out, right now it looks more like a description and it should be like a part of the name. Maybe put theKiteBar on top and Est. 2014 on bottom? or some other configuration?
Thanks!
