Okay I had this going in another thread, but since I decided to go with some HUGE revisions, I'm basically starting from scratch. I decided to zoom back out so I would have the whole region around the Mediterranean again, but I'm still going to use the Great Hungarian Plain as the basin for my fictional "Soaring Sea". I defined some lakes in the low points of the Mediterranean's topography, as well as extended rivers down into the now-Mediterranean Valley. What you're looking at so far is the basic planning outlines for the coastline, major bodies of water, and the river network.

And here is a blank version with some topography overlayed in red so you can see my line of thinking as for lakes and rivers. My mountain terrain (when I get to that point) will very closely follow present day topography, other than more containment around the Hungarian Plain - so the 'Soaring Sea' can exist as the highest altitude body of water.

I also decided on a MUCH larger image size (24"x36") - as well as printable resolution of 300dpi. So these images of the full map are at a GREATLY reduced resolution, for obvious reasons (the original image is well over 200mb).
This new rendition is an adaptation based on lots of great feedback I got from my other thread - which was extremely helpful in making this much more realistic and believable! So keep up the comments and criticism (so long as it's constructive!)
Thanks everyone!
EDIT: Also wanted to make a note - that tiny triangular lake where a lot of river's drain into in the middle of the Valley - a LOT of water drains through a sinkhole in the bottom of the lake. The sinkhole feeds a giant network of underground caves and caverns (called the Shadowlands). So if you're wondering where all that water goes that's feeding into that lake - that's where.
