Looks great. The dithering on the letters isn't very flattering - the dithered areas are larger than the solid fill areas. Compare with the dithering on the tree, which looks nice.
Background gradient has noticeable color banding, although it's tolerable at 1x zoom, & less-so at >=2x. Gradients are usually ugly outside of truecolor images - maybe attempt some sort-of
pattern dither (unattributed, forgot creator/s).
The colors are good but a little bland, Rydin's edit has potential but the highlights are a bit off.
