Yes the gimp. I originally created the rockmass in Vue but it didn't work out so I had to go back and draw that by hand. I then did the rest of it by hand in portions and pieced them into the picture. I'm not sure what you mean by "drawing and textures are swallowed up in a big blur" though. The ocean was created using filters in Gimp and then a slight up/down motion blur and then touched up with sprays of white paint and hand stroked. I'm still using a mouse so I'm sure it's not the best my hands can do

I'm interested to know what you mean though because there is always room for improvement, are the ocean colors too strong or are the details just not crisp enough in your opinion or is it something else?
