A few new changes
I reworked that tree trunk a little bit now and I think the shape is looking much better. I added a new rock which has given me a lot of trouble again, as rocks always do. I tried my heads at making a little dude to see how that would work and no matter how long I played around with his shirt, I just cannot wrap my head around shading cloths. It's like it never looks good?
Finally, I added a new little grass pattern to make things look a bit less boring, but I think I need a less saturated green for it to work?
Also, I now realize that it seems like I just took all the assets I had made and just spread them around, except maybe for the little arrangement above the character? I didn't want to have too much composition going on however because I felt like it would have been harder to c+c the individual assets if they were all layed out on top of each other everywhere. I will probably make a more composed version of this later to see how they would work in a real situation (video game, etc.)
Having a fixed palette ready for Ludum Dare might work. Should save you time.
That would probably help, but I've used premade palettes before (dawnbringers' and arne's for example) and they seem to just slow me down because I don't know how to make these colors work together properly, and I haven't studied them enough
