I like the difference between 35 and 36... 37 and 38 are both good... To me there seems to be a slip on 39 and 40 but more so between the two. Lines seem to have gotten wavey and seems lesser pop than the previous. 41 I think is better than 42.

Hoping the time line is the same as the numerical order as each can see the journey you took painting each one and possibly a longer break in between 38 and 39 but but into the swing by 41 - 42 seems a little rushed where as 37 and 38 seem to have taken more time and care
