well deejay I actually think that neck is the easiest joint to reach and can be hit from every position, while there are some points like the pacs that are hard to dm, so I think core boom are the hardest booms.
anyway tempo, even if I think decaps are one of the most important dms, also the head with the chest looks ugly, I really liked these replays, the kicks reminded me alot deejayy but you just need some better posing. uhmm overall I can say...8.8/10. didn't judge them separately because they actually looked really similiar :P
anyway I hope you could see my newest replay too :3
