Excellent use of the colours within those 16*16 tiles palette limitations.
My favorite parts of this piece are the staircase sections. They feel like the could have been in a Sunsoft game.
This is very nice. They look great. I'm a litte disappointed because when you put "unpause" on the avatar pic, I thought this would be animated. *sigh* But this is great too! Nice work!
Very nice. The only tiles I am not a fan of are the blue boxes, they are a bit blobby. Otherwise ace stuff.
You're just pumping these awesome mockups out like crazy.
And I love mockups.
This is incredibley professional work, like -DE- said I would also totally play a game with this high quality art:)
I love your tilesets in general. And it's really good that you share all this stuff. I'll spread the world about your work, I'm sure there will be someone that will do a good use of all this stuff.
You're absolutely brilliant.
All my respect.
Really great work.
Only things I dislike are the sand ceiling tiles in the first scene (are they just mirrored ground tiles because of the restrictions?)
And in the second scene the orange pipes seem to be in the foreground, maybe you should blend them more in the background for level-path readability.
Great use of tiling!
