Thanks, the dead space you see is actually just empty space as I finish coloring in the rest of my poster drawing. I thought I uploaded the original piece in the thread but I can't seem to find it so here it isThere is some really strong elements of compistion in this pic. The only dead space I see is just to the right of the Phantom's head. This clearly shows you have a good eye for design and layout, something many artists lack.
Regarding the rendering, I'm not trying to go for a 3D look. Best way I can say what I'm trying to go for is a bit of a more detailed Disney look without being lined in black.But while your layout is awesome, you need to work on your anatomy and rendering. The rendering can wait until later, but anatomy is what's important. Don't even look at a computer until you have a pencil drawing that looks great right side up, upside down, backwards, and sitting on its side. When it looks good every which way, then it's time to go the computer.
