I also notice that I like your diagonal sprites, even at this size they look well designed, how their limbs are positioned.
The sleeping/iddle animation is a also fine IMO, I love how she lowers her head to then fall asleep.
The way her arms move in the back-walking frame is good too.
Possible corrections:
In the animation she walks forward there is a white pixel on her forehead and on the idle image as well. It's an insignificant thing you would've picked up anyway. Lol
When she walks right and left, we can see a bit of hair in front of her ear that moves. I suggest keeping that hair fixed without any motion. Choose what position you prefer for it, it doesn't matter which one.
Because it moves in a way that it looks like it vanishes and reappears. Anyway I find it a bit odd, but if you like it like that, I won't boycott your game for it.
:p
@dahlys I love your chicken walker! Like others said the lines get blurry when the size is reduced.
One option is to simply fix some pixels after the image is reduced, if you want it more symmetrical.
I think it looks great already and moves so well.
:)
When I make sprites I do a lot of copy pasting So where the chicken walker goes left, I'll design the 1st image. Then I'd copy the top part of the walker (it stays the same in the 3 frames) and paste it in the middle frame + 3rd frame.
To make the walker going right, I'd copy the 3 left frames, mirror them so they look in the right direction, and simply paste all 3 in the Right direction.
It's the fastest way & the symmetry stays the same in all the frames.
If you design it on paper and then scan it in, instead of scanning all the frames, create the 1, 2 or 3 you need (side, front, back), and scan those only.
Then clean the pixels on the computer, and copy paste them to create the missing frames on the computer.
You'll notice the rtP characters usually look the same, both on their right and left side, it's for this "mirroring" reason.
I encourage you to use the technique you enjoy the most. ^^b Learning to make pixel-sprites directly on the computer will save you some extra time. But your technique has fantastic results already..
