It doesn’t look like anyone really saw this posting. I’m going to comment even though it was 146 days ago. Perhaps others will chime in.
Overall it’s a very athletic delivery. The only thing I can notice from this opposite side view is that his cocked arm angle is open at greater than 90 degrees at front foot strike. It may strain his elbow a bit. He’s also not following through fully and getting the most of his forward trunk flexion.
How’s his pitch location? Where does he tend to miss? Is he up in the zone to his throwing arm side?
