That is not who drew Makarov at all, its still the same as her original artist, hippos? the same artist who drew Type 97 Shotgun and G43 also drew Makarov. If you're skeptical about this, remember that Type 97S's halloween costume exists.
The coloring and her eyes do match Captain China's most recent art as mentioned by Hellscythe above (see post #3671307)
Also, apple54385842 seems to be more an info hub for GFL (like how Akancolle is for KC) rather than an artist him/herself. I'll change the artist to hippos until we can get solid confirmation otherwise.
Edit (09/04/2020): Ahh, thanks to the QoL update mentioned in the parent image, we finally know for sure who the artist is. You can check out his mihuashi page for confirmation (the post is found here: https://www.mihuashi.com/artworks/1678993 ).
