The "palomino' isn't a palomino at all, he's a cream champagne and probably isn't Belgian and QH but more likely is American Cream Draft and QH. I don't think he's well put together though. The photos aren't great for conformation critique, but you can see that he hasn't had good nutrition. His head has the overlarge look of a horse who hasn't had adequate calcium during his growth years, and he's got a body score of about 3ish in the first photo and a body score of about 4 in the second one. His legs aren't straight, either. I'd pass on him as prospect for anything other than a weekend husband-horse type.
Belgian x QH crosses are somewhat hit and miss. They tend to be on the shorter, stockier side. Good for general riding, but if you're going to do sport, you'll find that they don't have the athleticism you're looking for in most cases.
I have a Belgian Draft x TB (a PMU) gelding who will be five in June. We're doing dressage with a goal of making third level, and he'll be making his debut at first level this fall. We'll also be cross training in the low-level hunters in his six year old year.
Here's a few pics of him:
"Quick fixes, by their nature, fix nothing; that's why they're repetitive."
