I like the second one the best. As someone else said, maybe you have another light fabric that is not the same as the tips.
The blue looks nice too.

Ok, just saw the second group. I like the #1 and #3 of the second group.

I like #1 in the second set. The pale lavender in the background goes best with your borders, yet the fabric remains "in the background" without detracting from the deer. The green is just enough to give a forest feel.
I assume you are going to add stitching around your fused fabrics in the deer. If you do, then you can outline the antlers in a light brown or grey so that the tips don't disappear. Or, you can get a very fine fabric pen and define them by outlining them using that technique. It's also a good way to change the colour of a thread that you've used to free motion quilt, say on the deer, if you decide you don't like it.
Finally, I would free motion quilt a few "ghost" trees with bare branches using lavender or green (possibly variegated) in the background. Draw them first with one of those disappearing markers to see if you like the effect.

I love the blue one. What a great wall hanging. You did a wonderful job.

2nd set #1, it ties everthing togethor, but doesn't over power the picture.

I like #1 in the second set

I like the blue with the green at the bottom. It really makes the deer "pop." And it does resemble a forest and blue sky.
I also like the suggestion to take a pic and look at it for a week or so.
Which ever you choose, it will be gorgeous!

That blue color gives the deer a 3D effect. Love it!

The blue it lookes so like he is coming out of the field with the sky behind him!

I love the blue. It looks like that big deer has just jumped right through your cabin window.

My vote is the second set #5. You can really see the points on the antlers better. Whatever you choose, it is going to be beautiful.
