I sometimes do drawings like this as present together with the book. This actually for my grandmother. The reason why Brooks plays an electric guitar is that she doesn´t approve my main hobby besides the one I made my profession ( I love Stratocasters, but mine is sunburst not red) ….. This is watercolor and pencil.

Here is the link tho the making of the book:
