You mean on that picture of Jet Locomotive? I like Ilya's style, it is very sharp-looking. Thanks for the examples, I'll try to do something with lighting.
I would suggest using more tapered shapes in the beveling of the blades and other parts to add interest. It looks very boring with equidistant beveling/sharpness.
It's pretty sharp, but the composition is a bit odd - it looks more like a wrecked plane in a nest, due to the way the wood has been placed around the scene ;)
