Hi,
I like the picture. Especially how nice and contrasty the cloudfront is and also how for me it creates a line which my eyes follow through the picture. The glimmering relflections in the sea look also quite nice and enticing (nice, a bit metallic texture) although there seems to be some blurriness going around. Maybe jpeg related artifacts or something?
If you want to enhance the impact of the lighthouse in the picture, you might try cropping the top of the picture a bit and see how it looks (removing a bit of the clouds, making the lighthouse look more significant and balancing the sky with the sea more). This last one is highly subjective though as it depends on your artistic intent so see if you like it and go from there.
A quick note on personal experiences wrt. post processing. If you want to do a significant amount of post processing it's better to have the raw-files on hand (more detail and all that) as the in-camera jpeg engine may not always know what you had in mind. I also tend to have a long archive of originals sitting around on disk so that I can try and redo the post processing when I learn new tricks and generally improve in the craft. Couple of times I've gone back to pics that are a couple of years old and I never was really satisfied with and found that I finally knew what they lacked and how to do it.
There's lots to learn and discover wrt. post processing if you are interested on the topic, just try not to get overwhelmed and trust your own eyes first and foremost. If it looks better, it is.

Reason: post-processing...
