I already present myself in the "Introduce yourself" topic, but I'll make it again here because I think that re-introducing myself here will make you remember my name every time you enter here.
Hello everybody! I'm
Shackhal. I'm here to learn and to find
job doing pixel art

This topic was made to post the pixel images I make, looking for feedback and to improve myself. And one topic is enough to do that because having one place to post all your pixel stuff for improvement is better than creating lot of topics for every pixel art you make. It's more organized that way. And you can see all the improvement, right?
Ok, let's begin...
Some days ago I casually found Arne's topic from 7-8 years ago about his journey to make an all-around 16-color palette, so I also wanted to make a 16-color palette. The same rules (to use it on all purposes and cold, warm and cross color ramps) but with no-full gray ramp (including full white and full black). I made it using a palette attempt I made before, but I modified using his palette as an example. There is not to much difference between both palettes, I guess.
Now, I'm doing game mockups with it. Here's the first one:

It have all the 16 colors. Also, I'm not satisfied with the rock wall in the far background, but my principal focus that moment was the color palette.
I expect some feedback. Whatever you find is good enough.
