Good start. You probably could have gotten away with taking far less frames as the clouds and water weren't moving very quickly. I would reference http://timescapes.org/ and the forum there. Some very good information, and his work and the work of people that post there is just some of the best around.

I would pick a bit more of a stimulating scene for your next go-around though. Maybe if it were just a bit cloudier, you could yield some stellar results. Definitely try some night stuff too- stars are just totally awesome when timelapsed. It is much trickier at night- low light issues, noise, focus, etc. But when you get it right, its totally great..

good luck. Post your results!
