Love the expression, overall it's very charming.
Tourist, your edit kinda destroys the charm the original had, even though it's technically better when it comes to shading of the t-shirt among other things, but it's lost the original appeal and cuteness.

That's amazing.
I love the style.

I played around with it just to learn the palette and the style.
Only thing I have to comment on is that the sleeves look a bit short. And you missed the right white of the eye 

Just to clarify, the stuff I'm posting is old stuff from a few weeks back, they were done on different sheets, so I made the mockup to see how poorly they would match each other..
The only new stuff I did was the barrels, boxes and such.
Oh and those sprites are new too..

Decroded, if you don't mind, any help would be welcome

btw, Just to show how badly I'm struggling with keeping the same contrast and style:



Btw, if anyone feel like helping out, post a palette and I'll try to make something out of it, just for practice and getting used to more colorful and stronger contrast.

Wow, you guys are brilliant! I love this forum <3
That style looks really nice!
I think your explanation is pretty spot on too, since every time I tried to increase contrast it becomes very grainy. I actually considered making it more clean after seeing how the wooden floors looked without any grain.

The problem I'm having is that I tend to jump from style to style, I see something and go "oh let's try that!" and then next week it's something else
Right now I'm sorta trying to collect it all in my head before I start re-drawing the tiles.

A question, what method do you use for selecting colors in photoshop? I just have the standard color picker, but it can be confusing when shifting hues. Like a darker shade for wood becomes more red, but perhaps I need to shift it much further. I'm kinda bad at exaggerating colors and contrast as you may have noticed

edit:

Had a go at making some objects and tiles using a quite colorful palette.
It's really hard with the limited colors and it's also looking quite plain. I assume this kind of style looks best when you see the whole picture. But I had some trouble with the top of the barrel looking quite plain.
Ugh and outlines are looking quite messy in general, bah, need to do this properly when I'm not super tired and can barely see straight
