"Learn to paint in Acrylics with: 50 Small Paintings" by Mark Daniel Nelson is such a good book! I'd recommend it for anyone, even if you don't use acrylic or paint small, there's much to be learned from this.
It's very well written. The lessons are all about painting, there's no going off on tangents that don't have to do with art (many authors do go off on tangents or pontificate, I personally find it annoying when they do).
The lessons go from the basics to all sorts of wonderful lessons on shape and forum and brushstrokes, lighting and much more. Even though I've painted for quite a few years, I found this book to be so useful.
I did a few of the lessons. For ease of seeing the paintings clearly, the images will most likely be larger than the actual painting is.
This one is a lightbulb. I reused an old 3x3, so the texture is from the old painting.
This one is a balloon dog, which was fun to do. What a great subject!
This one is a tin and cherry, also on a used canvas. This doesn't look like much close up but from across the room it looks pretty darn good, if I do say so myself.
And this one is a red mason jar, this was my favorite lesson, I've never been able to paint glass successfully. This lesson was so clear and simple!
