did you use a tripod for this one? looks like you have some motion/shake blur. 1/20 for hand held is a bit tricky.
Learn manual, than use what ever mod you think you need to use.
For sunsets and sunrises i feel manual is the best to get the photo you want, because AV/TV will always try to give you what camera thinks is the right exposure, but in case of the sunrise it might not be the right for you.
Use RAW, as you will need to get most from your shadows and highlights.
Here are 2 posts that i started about manual mode 2 years ago. maybe i should finish the series:

Yes I used a tripod for that shot. That picture I posted was in JPG format.
That's what I need, thanks for the links, I will have a good read of those :)
Thanks for the advise:)
jpg is ok for posting, you shoot raw so it give you more options in editing, then you export in jpg.
