Little update here... still updating the whole image because the old water's just too ugly and spoils the look of the whole tileset. I updated it and gave the fire some tiles to be placed on.. I didn't really check whether those actually tile, but according to my calculations they..should. *scratches head*
Anyway. I'll post more later today, but right now my attention span is gone and... I'm not sure..
I used a lot of filters to make that water, so I guess the amount of colors in it is quite a lot bigger than it was before... I don't know how that's going to affect the palletting process of the tileset. I don't want to be responsible for messing that up, but I didn't find a way to reduce the colors in that area.
Also, according to Gimp, the dark color used in the metal pipes/wood is 0,0,0 , so wouldn't that make it transparent?
