Okay, gonna give you a few pointers.
You still haven't done anything but importing a BMP into the map editor, which takes about 2 minutes. You've painted on the terrain in the crudest manner possible, the russian steppes, as an example, are often more fertile than Spain, so maybe paint Spain with a bit of steppe?
Also, the snow line is well weird. Living in Denmark, I can assure you that we have very little snow here, much less than the alps.
Anyhow, my point is that this is not really download worthy, anyone making a mod will be able to make maps like this faster than downloading the .txt file and exporting it into their folder.
A few things you could start with would be smoothing the shoreline, making mountain ranges, rivers, trees, proper terrains, lakes etc. Everything that gives a map that special feel.
I've spoilered a map of europe I worked on a while back and never finished below, maybe try and emulate what I've done. Map is far from done though, so don't forget that terrain changes, trees etc., are all very important.
