Very nice, Good job. But It is called de_dust and the green tiles doesn't fit on de_dust! But it is awesome I wont rate 4/5 or less because of that. Good job 5/5 for you
de_dust -> de_spring? I like the bombsigns. The transition from grass to stone tiles is also very good made. Only the water looks a bit like quicksilver. This tileset will probably inspire some mapmakers to make new maps. A solid 5/5.
