I'm not sure if it's rock or cloud, but it's the middle section of what look like the three sections or rock just to the right of the wing... it looks like a gorillas face in brief outline... it actually is very cool, I think, it gives an exotic feeling to the whole piece (which is incredibly beautiful by the way - have you done any professional work yet? I think I might hire you in the future when I have my big project underway, let alone still actually get a copy of the piece you made for me...) I'm very obsessed with images-inside-images, so I tend to see them even if people don't mean to put them there. I think your style does that -very- naturally... I'm trying to find this image by a guy named Hans-Werner Sahm on the internet that demonstrates really beautifully what I'm talking about... it's literally hanging on the wall right next to me, but I can't find it on the internet to show you, and I don't have a camera... Bah, well anyway! I thought it was very enticing. Always makes me happy to see new work from you
