So, as I said before I was to post my WIP thread soon. I am usingThis Tutorial here.
Here is the base I began my work with.
After I finally figured out the coastline part, I just dulled down the blur he told me to use in the tutorial and it fit better, giving me a more solid look that I could be okay with. I followed all the steps and then experimented with the Smudge tool. This is my sea mass as of now.
So, I am off to attempt the landmass part now, wish me luck and please give feed back on my progress.
