Nice land shapes! - that's coming along very well I would say.

One thing though - is the image meant to have a drop shadow 'frame'? Looks like you've stroked the land and blured it but forgot to delete where PS selected the edge of the image. So you've got a drop shadow effect on just the land. Deleting those stoked areas before you blur it will clear that up.

I also like the faded, lighter areas of the land / image. Looking forward to seeing it develop!

Good work.
