I like that little house.

2x or 3x looks extremely better. I like the idea of it, and the shading is a start.

It reminds me so much of Knytt Stories O.o

oh, and we usually don't want stuff submitted above 1x, but if you preferred to display this at 3x or so it'd be fine, being that the piece is so small

 Thanks!  I'll experiment a bit more with posture, clouds and coloring.  Doh, I hadn't thought of posting to the forums- I'll definitely do that as well.

sounds like a pretty cool idea. their arms and postures are a little block in the first and second pictures, you could make them slightly more naturalistic if you wanted, but I think blocky works fine here too. The contrast between the blue of the ocean and the blue of the piers in the ocean is too small, I'd make the ocean a little lighter, or the pierblue a little less blue and more brown. Clouds are kinda goofy shaped, I know  it's not necessarily naturalistic, but I usually draw mine with flatter bottoms and billowy tops. bearded guy seems to have a short jaw, you could extend the beard down a pixel, may or may not look better. this is all just me searching for crits since you asked though, they're pretty good overall. Also, if you want more in-depth critique on further graphics for the game, you could start a thread in the WIP forum.
