Ya, in the right lighting or from a distance, Maul's eyes are effective. I love my Maul bust, but I can see and agree with those who see the eyes on the 1:1 busts as an area with room for improvement, probably the only flawed area.
Here's my Maul bust, looks pretty good zoomed out.
Same photo, at full pixels to show the eyes closeup.
Now, had his eyes been done as detailed as the films and the bust eyes executed in the same manner as the T-800 bust, the Maul bust would have gone from awesome to a level that couldn't be described.
The issue is, with Maul, the eyes are important, but not so much defining. His tattoos and horns make his whole face a complete look that you take in as a whole. With Palpatine, so much was defined by facial expression and specifically eye expression, in ROTJ, so the eyes become a crucial detail in that bust. I'll be happy with this bust and get it regardless because of how much and how long I've wanted it done, but I stand with my bretheren hoping for the eyes to be the best they can be.
