this is my first isometric pixel art piece , i made it following this tutorial :
this is the steps i took to finish it :
i didnt realy care about color conservation or anything like that ...
@Altourus i created this in MsPaint and saved it as BMP then i took it to Photoshop to make few edits then save it again as PNG .... this might be the cause ...
On a side note it says you used 32 colours, however http://wouterpleizier.nl/pj/index.php?input=http%3A%2F%2Fwww.pixeljoint.com%2Fpixelart%2F87400.htm says you've used 48, was there a saving issue? If you save to jpeg extra colours will usually get added.
