Fantastic Art instructional book. The ratio of text to example images is better than any I've seen before. I found myself exclaiming "huh" or "dang" multiple times while reading because of unique tips and tricks I've not seen elsewhere.
I was very wary of the "parallel text," but the English is very clear in almost every case, and only awkward in two or three cases (I can't speak for the Korean).
The instruction definitely is in a particular style. It's one that I like, but if you're looking for realism this wouldn't be the way to go.
