disappointed? soz graphics god. well maybe it's because we'd rather admire it than criticize it, or we just don't see the need to criticize it cause we actually like it? i wouldn't even know where to begin with 'constructive criticism' anywayDisappointed by the amount of replies yet lack of any real constructive criticism.
A few issues I can see by looking at it:
1. Shading and colours
The shading is a bit... off. The box furni, for example, I don't get why the closest corner is not only the brightest part, but also a pure white - it shouldn't be. The colours used for yellow are bad too, but I've always had some difficulty shading yellow. You should look at some actual yellow furni and see how "professionals" do it as a means to understanding how to properly select yellow colours.
The light source is also a bit off in some places so make sure you keep an eye on the shading you do and that it all is lit from the same direction(s).
I also don't get the shading in the toad hat, is it meant to be indented in the blue bits? If it's meant to be smooth just shade it with the rest of the hat.
2. Transformations
You can't simply rotate a sprite and expect it to look like it should - it won't. Rotating images will just mess with the perspective and make it look imperfect (it will also mess with shading!).
I would also say, though this is a more personal preference, not to use the same tile size for small and large Habbos and not to mix them in the same section. They literally just look like tiny Habbos at the moment, rather than it simply being the camera "zoomed out" if that makes sense.
3. Outlines
You seem to bounce between black outlines, coloured outlines and I think in at least one case, no outline? As far as Habbo is concerned, you should really stick with black outlines for the most part. The only time I would personally not use a black outline, and the times when it seems best not to use a black outline, is when it's the same object in a fairly small area in which case you would probably just use a darker colour of whatever the black line would be against.
4. Shadow Inconsistency
You included shadows in some places, but not in others. Not much more to it than that.
I think that's about all I can see at the moment, definitely some potential but nobody is without room for improvement.
