Good solution on the wordmark the "R" looks great. Also like what you've done night sky and better palm trees. I guess that's why I've ranked your design 1st so far. Not sure what to say to improve it... some things I would like to try if you have time
-having the black border or some other type of border on the oval an even width around the perimeter
-not having the ukulele so prominent in the design. check out the website koolauukulele.com. I really like the feeling of their logo. "more about the feeling of someone playing in a beautiful setting"
-possibly some water int he foreground? moonglow reflection on the water?
-possibly just a touch of some color in the sky like late sunset
-Also check out
http://harrywishard.com/artist/wishard-all.php for some great ideas on the feeling I'm going after. Obviously not detailed work like this but the paintings depict the type of imagery I'm looking for.
Thanks again so much for your efforts.
aloha,
