Oh no. It's not a WIP. With "improvement" I say in the creation of pixel art in general. I'm still learning. And yes, it's the style I'm looking for. Thank you very much, it will help me a lot!
If you're planning to change your submission based on feedback, it's technically a WIP and should be posted on the forum, not in the gallery.
This isn't exactly critique, but here's another take on the same scene. I tried to focus more on the forms of the hills and tower and not rely so much on outlines. Outlines tend to flatten things, and in the case of the tower, you have double-outlines, which look odd and flatten everything. I also made the sun's reflection a little brighter towards the middle, which I think looks more natural.
This might not be the style you're aiming for, but maybe it'll be useful anyway :D
simple and stunning
