I usually freakout when I find a great illustrator... but this time I've found one that just blew my mind. His name? Loopy Dave. The man knows his thing.
All his work is pretty rad, reminds me a lot of Serge Birault's work (Dave even makes little homages to Serge in his work), and Dave's work is absolutely full of detail, an that's exactly what caught my attention. People, look out for hands, muscles, feet (man, the feet are just amazing), girl's ribs (this one just amazing), fabric and lighting. That said, you may just go ahead and appreciate his work. Don't forget to check out his portfolio for much more great pieces! Enjoy! ;)
