Nice. The second one is definitely the better one -- if you look at the first one at 100%, you can clearly see out of focus areas with other in-focus areas both in front of them and behind them---you need more exposures and/or they need to be closer together.
Here's one I made recently, which has the same problem---my exposures were too far apart, so there were some areas where there was no in-focus frame to select for that area. This was 13 exposures.
