Looking pretty nice, like the color scheme.

...however...

You have some pretty major river violations. This is a fairly common mistake for new map makers (I did it myself any number of times). Rivers rarely split as they find there way to the sea/ocean/etc. Generally they converge as travel from the high to low. Also a lake may have several 'sources' but almost always has only one outlet.

That being said, if you have a reason for the rivers being the way they are then by all means ignore that last paragraph.
