I think the first one might benefit from a tighter crop - the reds around the sun look great, but there's too much black all around. I'm not sure about the second one - there's something missing, I just don't know what it is kudos to you for getting out so early, I'm lazy so I only shoot sunsets
They are both a tad dark, but I can tell you were exposing to not blow out the sun. If it bothers you, you can look into HDR.
On #1 I also would like to see a tighter crop, get rid of all the black space.
On #2 I dont think you should get rid of the ocean, perhaps take a bit off the right to put the sun more in the rule of thirds space? Since you went dark, the water looks like it has a nice moody feel to me.
