Sure, let me tell you what I see now that I'm on my laptop.
Goldmaker is slightly over at the knee, as is your mare, which is something I like in a performance horse. Many racehorses are bred to be slightly OATN because it's believed that it aids in longevity and holds up well to concussion. His shoulder is near-perfect, which will hopefully improve on your mare's slightly upright shoulder. Goldmaker has a very solid build. He's not as refined as some of the other horses you're considering, but he will hold up well to what you want, which is an all-around STURDY horse.
There are several things I don't like about him, though. His hindquarter is decent but not fantastic, which is unfortunate, as that's something you definitely want to improve upon with your mare. He doesn't have a huge amount of bone, but that's not something I would worry to much about, as your mare has great, substantiate bone. His neck isn't as long as I'd like, and neither is your mare's, so again....That's something that will not be improved much with this cross. His gaskins are not very strong.
Now that I'm on my laptop and can see the stallions easier, my favorites have changed. At the top of my list are Color Guard, Diamond Stud, and Sempatico.
Color Guard is simply fantastic. His pictures weren't showing up for me before, but now that I can see them....wow. I simply can't find fault in him, other than slightly-too-long cannons. His shoulder is excellent, his neck gorgeous, and he has fantastic depth of heart girth and a strong hind end. His hind end isn't as strong as I'd like, though this is downplayed in the conformation photo as the photographer is standing in a very flattering place slightly behind the horse.
Diamond Stud is right up there with Color Guard for me, and I feel he would compliment your mare equally as well as CG. His shoulders are massive and have a perfect angle, which will really improve on your mare. His back is short and strong, as is his coupling, though there's something that looks weak to me along the rear of his topline that I can't put my finger on. His neck will be a great improvement to your mare's, and his delicate head is an added bonus. His legs are clean and straight with strong gaskins and great pastern angles. He looks to have strong hooves.
I'm surprised I like Sempatico as much as I do. He has a really nice build that is both solid and athletic. He lacks depth through the girth and is quite slight of bone, especially in the front legs. His hindquarters are nice, though still not as strong as I'd like to see, and his refined neck ties in well to his short back. He has a solid, compact build that I think is just athletic enough to add the right amount of refinement to your mare. I can't see his hooves well in any of the pictures, which concerns me. Your mare looks to have great, solid feet, and I wouldn't want to mess that up.
I'm still a huge fan of Sir Wanabi and think this would be a great cross. Just another stud to consider
