The first one has many problems.
The ear butts are terribly low, the earliners are shaped bad, as in too pointy at the tip. The skull plate is mounted too high on the mannikin. The inner ear skin is drummed really bad and is not placed inside nearly enough. The dark hair should make the bend and go into the ear so that there is a ring of black hair on the inside of the ear cup. The nose is not thinned nearly enough and needs tucked into the nostrils more and taxi'd better. The lips are not tucked nearly enough. There should be no lip showing except for the very front under the nosepad. The eye clays are not substantial enough for a mature deer and the eye shape itself is not even close. There should be more skin taxi'd toward the eye from the back as the hair patterns are pulled out of place. The tear ducts look pulled, and are probably not thinned enough. There seems to be wrinkles in the neck that have the hairs pointing in various directions from not being taxi'd correctly. All the problems are typical of a first attempt and should be expected. Just a shame it was such a trophy that was experimented on. The second deer has many of the same problems but seems a little more improved. The next deer pics look quite a bit better as they progress, I'm sure you can see that. I'm not trying to beat him up here but these things are obvious to me. The eye shape on the second two looks so much better that one would think it was done by a different taxidermist. Tell your friend to get some good reference pics oflive deer, their noses, eyes, ears, earbutts in various positions and study them thoroughly and have them handy when mounting. The missteps will be obvious when he looks at live reference. Never look at pics of mounts as reference, only live deer. Hope this helps.
