it's a shame, It's a great concept idea and scene. Please take the time to make this piece pixel art approvable! I suggest using the WIP forums
On a positive note, it's a cool scene. With one small image and a line of text you've set up a basis for a story that viewers can create in their imagination when they look at this.
Not pixel art. Background and some objects were brushed or textured.
One tip is that when you do pixel art be deprived of a color palette, not these 464 colors that you used.
the black outlines stand out quite a bit..
give the colors more contrast..
maybe some little looped animation could be nice... like the drill spinning and the lava glowing, maybe some rocks falling down ... and some sort of speech bubble dialogue
I wish there was a game with digging ducks! They are so cute and funny!
