Old alien pic

I made this drawing a very long time ago when I was drawing with acrylic pencils on paper. I took some pictures of some old art and I thought I'd make this one in Photoshop and just show you how I evolved as an artist (or drawer as I call myself haha) and show you the reason why I love Photoshop more than acryllic pencils hehe.
