Those loads look good. Congrats on the PR.
If you care, I thought I may offer some advice. One thing you will get better at as you do more loading is figuring out how to put the minimal amount of effort into the load required to get it onto the platform. That means setting up so that the high point of your load occurs right at the edge of the platform. Notice how on your first stone you killed it, which I assume what your intention. However, your high point occurred a ways back from the platform.
Your second load with the heavier stone is probably closer to where you want to be standing (leaving out the twisting around part ...lol).
Again, this is not an issue with those stones on those barrels for singles; however, when loading a series of stones onto a slightly higher platform it will become essential for you to maximize your efficiency.
