I made a couple of small errors but dammit I did it. I bought it for my birthday almost a month ago, to see if I had the dexterity in my addled hands and brain, and the answer is, I do!
No art pictures on these, I just built a predesigned wooden model kit, no real creativity, just instructions and endless dexterity rolls.
My wife and I have done two of the book nook kits now. Trust me when I say making it an evening activity for two halves the difficulty.
The one you have done looks amazing - IMO the mistake work.
