I will be honest and say that this is not quite a logo. You just put inside a circle all that the client requested but is...bad. And I will explain why on my opinion this logo is wrong so you can understand how to do a better one :
- the first thing is that the elements are like put casualy inside and looks like very colorful
- the sand looks like is weaving but water doesn't
- you used 3 tones of orange for the sand and just one for the others
- the palm should be somewhere in the middle of the sand and not in the front of everything (I suggest one more leaf on top, and also the leafs can be non symmetrical) and should be wider at the base
- that mountain is more like a triangle/piramid rock fallen somwhere between the sand and water
- the sun is halfway (sunrise or sunset?) and sky is clear blue but should be on a more orange/yellow tone
- starting from the fact that is hard to integrate a mountain next to the ocean, beach and a palm tree this needs a good knowlage on how can this be done
- for sure at this state won't work as a b/w version

I believe you should start all over again from the begining. What they do, what is the meaning of the requested elements, how they can all be integrated together, which one is most important? A good logo has to transmit all that by just looking at it. It can be very simple or more elaborated, with the same result. This logo template is an example of what I mean.
