The hiking trail isn't a problem for me, most wouldn't evn notice it.  You have really captured the time of day with your processing and the blend looks excellent to me. Was this only 2 exposures - 1 for land, 1 for sky?  The lupine compliment the sky color.  Any tips on blending the sky with land appreciated.  Looks like some fantastic hiking there.

One of those that has to be viewed large for the dark background. Great idea to go with the starlit sky, it makes for a wonderful mood, and you did a splendid job of working with the flowers you had. You could clone out the trail pretty easily; I think it would make the left side less broken if you did.

Another sweet one, Sairam.  I would also clone the trail, just to clean up the left side.  Very nice.

RAd, great job with the blend. 

Sairam,

Definitely need to view the large version to really appreciate this.  Honestly, I must mention my first impression.  For some reason there is a disconnect between viewing wildflowers in a landscape.... but then viewing them in twilight?  I mean, who goes out to view wildflowers at night?  BUT, I realize your story and we often find ourselves out there in the field and just can't get done what we want before the sun goes down.... and I often say to just deal with the conditions we're in and make the best of it.  And you certainly did that!  The large view actually convinced me to discount my initial impression.  This is beautifully executed. The flowers have enough light to be appreciated, and yet there is enough darkness in the sky to allow for the stars.  Quite believable to me.  Well done.

The larger view is certainly a big plus. I agree with Lon the night does not provide the best light for viewing flowers, but this is well done.

The large version looks very nice as all of the detail in the foreground shows up nicely.  The stars are also very clear and show up nicely as points of light.  I think the composition works well with the repeated diagonal lines. 

The blend looks very nice and I like the comp very much. Nice balance of elements in the frame. I may look to reduce the highlights/increase contrast on the horizon to give this more of a night look. At least to play around to see how it looks

Thanks for the feedback guys! Really appreciate it.

Harry, for night/twilight blends, I take one image about 20 - 30 minutes past sunset at a low ISO and one image about an hour past for the stars at a higher ISO. For pre-sunrise twilight, it's exactly the reverse process. For this one, it was a little more tricky. I took 4-5 images as part of a focus stack since the closest flowers were inches away from the camera. Then I took an additional image for the sky at a higher ISO to get the stars. As for blending, I have found that using the lighten blend mode really helps avoid any noise issues from the star image since the stars the brightest parts of that exposure. The key though is to balance the brightness and white balance of the land exposure and sky exposure so that the blend looks natural.
