Just something I did in graphics gale back when I was interested in pixel art. Use as you see fit.

The preview and the file itself are the same but the preview appears to have been blurred so makre sure to actually download so the pixels are clean.

from left to right, top to bottom, the sprites are:

rabbit
vehicle1
vehicle2
cat jumping1
cat jumping2
cat playing
chainlink fence
chainlink fence broken
picket fence
plank fence with grass
campfire1
campfire2
campfire3
campfire4
campfire5
grass light
grass dark
various helicopters with blades
helipad
junkyard scrap wall
train track alternating
train track regular
train track dense
road
selector
stairs1
stairs2
pine tree
broken telephone pole1
broken telepphone pole2
various other telephones
vehicle3
pickup truck
delivery truck
small pine tree

Each tile is 32x32, some of them are centered, some of them
obviously need centered. Background is mostly light against
dark except for helicopter, helipad, rabbit, cat, grass
variation, and the selector.
Slice as you will and rearange to suit your needs.
