Pretty decent, with the contrast and greyscale look. It doesn't always work that well, but it's pretty alright here. Usually I prefer monochromatic-esque stuff to actually have color, somewhat like Westonini's Yellow-Orange range and the Cyan-Blue range I normally aim for in my art here. The composition is alright too.
Also, I'll probably try to expand on my avatar someday soon, it's been a while since it's been updated.
