I had a similar situation with my Rocky. When I dropped it off, I told the guy working there what I wanted - wall pedistal - and I specifically told him to not tip the head down like a pronghorn that was there.
And you can guess what it looked like when I picked it up. I took it home and put it on the wall. My ram is a 3/4 curl and when you tip the head down, it makes it look like a 5/8 curl ram.
After a couple of weeks, I couldn't take it anymore and took it back. I told the owner the flaws I saw in the mount and he said "What do you expect? It's not a competition piece".
They were able to soak the hide off, tip the head up (too far this time) and then put it back together. It came out ok, but it isn't exactly how I wanted it.
If you are going to take back, you probably should do it soon....
