Been working on this for a while as practice on lighting and reflections. Got kind of annoyed with it several times but I think it's as done as I'll ever get it (with my current skills at least).
Not super happy with it overall as I think it's still a bit messy but I couldn't really think of any particularly good ways of cleaning it up while keeping the bricks looking roughish and not increasing colour count by a lot.
Anyways, hope you like it, I'm gonna work on something blue or green next. I'll edit this section with a WIP gif later.
Used this piece: http://www.pixeljoint.com/pixelart/75085.htm from philippejugnet as a ref for some of the shading on the bricks - wish mine turned out as well as his did!
EDIT: Added a couple of small tweaks based on felchqueen's and ADrawingMan's crits. Thanks again guys!
EDIT2: Tweaked it and cleaned it up a little bit
