You have really improved, but your still lacking alot,
1. Saggy boobs?
2. Anatomy? ok..so how the hell do you cross your legs?
3. Base seems to have a hint of pillow shadeing,
Made a small edit to show you that more colors, and more shades is absolutely beautiful.
It gives more detail into the art and adds more shading.
Also fixed up some of the anatomy for the stance.
I prefer the big base just for its size, but remember if you improve the base size you have to improve the surroundings too, otherwise it shall be like giants, one thing i would do is google the stances your base is taking and make sure the proportion is right.
Also colour definition on objects is a must imo, see the box, show that its not flat by adding some volume to it.
I definitely like the smaller sprite better :p. ... .... Nooooooo I can't even lie lol! I like the bigger sprite better because it actually looks well done. Well, it could use some work, but it doesn't look like straight up beginner work like the first sprites. They looked... unworthy for you lol.
But, I agree with the others. You should really fix where the knees bend when the characters cross their legs. It would definitely look a lot better. The colors, I really don't have that much of a problem with, however it would make sense to make them a bit more colorful :p (Not just the sprites but the environment as well) . It would certainly look more attractive that way. Would bring that, uh, One Piece feel into the game :).
I actually look forward to trying out your game brah, even from the work you posted here so far. It may need more work done, but it looks passable in my book...though passable isn't always the best, so keep working on it :D! Good luck to you man.
