I love The Colonel, Los Hermanos, and In Aqua Caliente, though it's hard to single out only a few. They are all very strong. Thanks for sharing and I look forward to seeing more of your drawings as the exhibition nears.
Gracias amigo!
I update new work on this forum from time to time and also have a blog (link below) which shows new developments
My exhibition of drawings is in May (if you happen to live in NW England!)
