Overall, great wallpaper. :)
I actually like the background; I love how it draws the focus to Len's face.
I just really like the overall... ethereal feeling of it~
Beyond that, I would have loved to see some more detail in his eye, and maybe a color for the background that contrasted
more with Len's coloration.
There are some lines and shapes here and there that don't connect or extend too far if you look closely, but even
people who have been using vectoring techniques for years miss those little mistakes, so I really wouldn't sweat
that.
Again, really great wallpaper. The world always needs more beautiful Len wallies.
Keep up the fantastic work!
