(This is first feedback, sorry if it's not great)
Tree:
The trees leaves seems to round, which is okay, if you want that style, although the shading almost implies it's more of a cylinder that is tilted sideways. By making it less 'gradient like' (I know it's not a gradient, still, best way to describe). You can give the tree more depth, and a sense of 3d. You can do this by having shadows that are lighter and darker at different angles within the leaves. It, to be very critical, also looks strange having single pixels, as in a tree, if light is hitting a certain part, it will light up more than a tiny spot, even if it is just a leaf. Also with the tree, the shading on the log is left to right, when the shading in the leaves is up and down. Like the trees leaves, work on making it have more depth by not just having a squiggly gradient, but rather having darker patches to show shadow from the leaves, and shadows where real shadows are. Look at how real trees like, because the are round, the right most bit is not always the brightest, sometimes it's in the middle. Look on google images perhaps.
Player:
The player looks best in the first image to be honest. The lighting on the other too is very off. Try to avoid just having dark shadows around the outside, as it's not like the player is flat. The shading in the cap is fine, but ensure the direction the light is coming from is consistent. The legs and body need the most work, as they seem like paper, having no depth, as shadows are nowhere clear except the outline. The first characters kind of cute haha.
Tileset:
I'm referring to the ground and walls here. Overall this was my favourite part of the image. Colours are fine, but again, but again, the shadowing doesn't make sense. However, unlike the other elements, I don't mind it, as dirt can be kind of fuzzy. If you wanted it to be more detailed, you could have general rock shapes with clear lighting and shadows. No real feedback here, I don't mind them.
Apologies for not using the best English here. I was using a friends Internet, on an iPad, and this is my first post in this section. Hope this helps!
keep going, looks good. Sorry if I was a bit too critical here.
