Yes I realise now that you are all right about the shadows. I made an other copy 2 days ago that I exposed 4x2 sec. The one shown here was 3x2 sec. After drying down the new one was too dark. Highlights on the snow were still there but not as bright and the shadows were too dark.
It is thrue what they say, you really have to LEARN to see.
Thanks all for having the patience to teach.

Hmmm... Those are pretty 'short' exposures you're using there.
I don't have a problem with the way you aggregate exposures (2+2+2 etc..). I don't do it myself - I add the test exposures together and give a long unbroken final exposure - your method can actually help exposure accuracy, especially if the bulb in your enlarger takes a long time to 'warm up'. (On the downside, it turns dodging/burning into a, somewhat less interesting, imitation of coitus interruptus...)...
The problem is that, by using 2 second increments for your tests
and arriving at a 4 or 6 second final exposure, you aren't seeing a wide enough range of test exposures to make an educated choice - hence your original error in exposure. I think that it would be helpful if you reconsidered the way that you use apertures when enlarging.
In your example, the difference between your first and second exposures is almost a factor of two and that's a big difference in printing terms.
You can use your method successfully - I've seen it done by world class printers - but as a beginner, you may be missing some of the options open to you and, so, be making less well informed decisions.
If, when you do your test strip, you were to to close the aperture down by one stop more, then this would give an exposure
in the region of 8 secs, giving you four (or more) comparison strips to choose from and allowing you to make a more informed choice for the final exposure.
And... If you closed the aperture by two stops, then you'd be getting an exposure
in the region of 16 secs with eight or more exposure strips to choose from, thus enabling you to narrow down your final choice even more accurately.
In short, I'm suggesting you "optimise" your exposure times by using smaller apertures.
Longer exposure times allow you to accomplish dodging and burning more comfortably but, more importantly, it also means that you have a wider range of exposures on which to base your final decision - making it easier to choose the right one (plus, the 'reject exposures' can also be used to help me estimate dodge/burn times, too).
Personally, I try to choose an aperture that will give me exposures in the region of 15 - 30secs, sometimes longer...
Dry down is a separate issue. With experience you'll learn to gauge it visually. I did try the Ansel Adams method of using a microwave in the darkroom, but I had to throw it away after an assistant attempted to nuke a Ginster's Pastie...
