K. What I think you should work on first is the colors. Specifically, the browns. Try to get away from thinking that if something is predominantly one color, that every shade it uses is the same color but brighter or darker. That's not the case. The color of the light source is what will determine what colors the highlights and the shadows go to.
For example, since it's outdoors, the sun is the light source. That makes it yellow. So for the highlights, they should have a bit more yellow in them. You don't need to make it pure yellow, but just yellower. For the shadows, you'll need the opposite color of yellow, which is purple. (Look up complementary colors in google if you're interested for other colors). So, the shadow colors should be more purple. It makes it more interesting than if it's just light brown, brown, dark brown.
For the tree trunks (and the leaves), I'd recommend you see what direction the light is coming from. Most people use top left light. So, the left part of the trunk would be bright, and the right part of the trunk would be dark. You don't need to apply a texture to the shadowed part either, though you can if you can pull it off. But yeah, when you're doing a texture, first see which parts are bright and which parts are shadowed before you go doing the texture. That way the object doesn't look flat but it looks more 3D.
More contrast with your colors would be good too. Not so much for grass and floor tiles, but with objects, you'll want each color to be seen.
