Thanks for reading it! And you're definitely right, some of my book work tends to over-explain some things in a couple of places. It's something that I've been trying to fix in my writing over the last few years, but that I sometimes have trouble with in long book pieces because I literally forget if I mentioned it or not, and then I don't catch it in editing because I'm trying to edit a bit too quickly to meet deadlines (that and I am nowhere near being able to afford a professional editor to catch them). I really appreciate you letting me know so I can keep it in mind as something to strive to do better on in future books.
As for illustrations, I never actually thought of doing that! I'll keep that in mind for later works as well. I initially thought I might stick in some screenshots, but figured copyright rules could get dicey and didn't want to get in trouble.
