I don't get why you place the shadow of the trees leaves right under the tree, like it's twelve o'clock in the afternoon. While the trunks shadow seems to be alright.
I think the new tree is way better.

I've tried again regarding Hideons trunk study. My last tree didn't have a trunk texture. So, tried to improve that.
You also added roots. Since my tree haves to be in a platformer game I'll have to make a flat base. But I have made roots on the sides.
Also changed the palette again. It's really hard to get the colors right. Better?

It's just a part of a bigger tree and is not finished. I posted it now because I was wondering if I'm going the right direction now.

Hello,

I know there are tons of topics about trees, I've been reading lots of them, but got stuck anyway.
I'm trying to draw a nice tree. I have tried three times now but I am not to satisfied about the result.
The third one is the newest.

I wanted to make it even bigger, but I decided to start out small to get the shading right.
I hope you can help me improve it.

I really like this style and this one looks good to me. It gives me an awesome I-am-in-a-huge-empty-city feeling. I don't like the hard black of your character. It makes it look like the charater is standing in front of the environment, instead of in it.
It's a funny choice to make the gun pink. I think it definately fits in the style, but it doesn't look to deadly. What about red?

Maybe it is also woth trying to swap the yellow and purple colours, so the corridor is bright and the background dark.

I'm not nearly as good as other people on this forum, but I tried to do an edit on your princess sprite. I think you should try making her stand a little more natural, lik a human instead of a robot:

I hope you can use my advise.
