Here's my ding bu - I hope it's akin to my master Decheng's since he taught it to me. Mine photographed from a slightly exaggerated angle, but I too keep my elbow tucked in, mostly for that qinna app.

I've seen a lot of variation in Xiaohong quan, even more in Dahong. There's an internal temple version that's really different - same moves but an almost chen taiji-like energy. I've even seen variation in the lyrics and once started to compile those variations, just for fun. The essence is usually the same, though.
