A war tileset :)
Ok what i mainly like about this tileset, is that you have a clear topic, and you have two site , unlike the usual blue/red you have spain with the brown basics and the war green for france(I suppose). I also like your color selection for the tiles not too funky rather settled pastel.
The masks works fine with me and i definitely like the spaz/jazz warriors :D nice job.
What you clearly miss out is the optimisation of the palette see layer 8(ask other ppl(notme) for some help if you have problems :) cough*disguise&toxicbunny*cough). Moreover does the tileset lack in eyecandy you have some detailed eyecandy part in which u certainly put some effort in, but they can’t fill a whole level. You are missing out layer 1,2 6,7 in my opinion.
Finally, I think your idea for this tileset is good and you have creativity, just get a bit more into those points i mention above.
