The first I'd like to mention is In the Wilds by Nigel Peake. I was bought it as a gift for my Birthday and is a beautiful book. It has a sort of linen texture cover which is very appealing. Inside are almost a hundred drawings in ink, pencil and watercolour inspired by the countryside and rural life. I've found it very inspiring and can highly recommend it.
Predictably I love the birds he draws
I love the way he works with pattern too
