Some thoughts ...
I like the font you've used for ocean text, but I feel like it needs tweaking. When I zoom in, it looks OK, but at smaller resolutions, some of the finer parts of the letters are overwhelmed by the stroke. Also, I feel the hard edge of the light-coloured stroke doesn't quite fit. Maybe if you tried blurring the stroke, it would soften the edge yet still allow the letters to stand out from the background?
With the title, I love the design and I think it could work really well, but something nags at me and I can't quite put my finger on it. I think maybe it's the use of very similar colours to the land masses. I see your textured lands with lumpy bumpy bits, then I see the flat text and it feels disconnected. I'd maybe try some sort of bevel or shadow on the text, or simply try a solid colour. My vote would be for a solid colour or subtle gradient to contrast with the colours of the land.
Anyway, just my thoughts. No doubts others will have differing opinions!!
