Check this tool, it might help you with color count =)
You can figure each color's location by hovering over the swatches. You'll notice (at the bottom of the list) that some colors are used for very few pixels, that one or two appear in your palette but nowhere else, and that there are 3 semi-transp colors, likely accidental.
This would have much more appeal with a background, even a minimal one. Also needs more contrast.
The antenna wire on the other hand needs less contrast! Consider it would be much thinner than one pixel, its color being spread over the whole pixel mixes with the surrounding brighter tones. That's what our brain expects (and reads) from small details in raster images.
Very sweet iso pixels, serious skill there. Color palette is bigger than you think, at this point you may want to update or preferably remove your color swatches from the image (they only detract from your work) or do a palette consolidation step and bring your colors back to your original palette.
this is quite fine house indeed... but perhaps we have different definition of limited colour palette, to me 34colours is a huge palette
Hi! Not sure if you still visit here, but I was looking at your buildings at PixelDam's site and wanted to comment on how nice they look. Great job!
