Hello and thank you for the warm welcome :)
Thank you for the advice, very useful to know. Even the pj image inspector looks quite useful. I will experiment with dithering and streaks, hopefully I learn the terminology quickly too!
Thank you kindly!
Hello and welcome. Your first pixel art is beautiful. However, since you have used a gradient as your background, I must inform you that we usually do not accept such pieces in to the gallery, because it is not a pixel art technique and it artificially inflates the colour count beyond the artist control. We require all pixel art to be hand made with pixel art techniques. For a sky like that, it could be any form of dithering, or some smooth, long clusters. You can inspect the details here
I'm accepting your first pixel art, but please watch out for that in the future.
@BleuPale: thank you kindly :)
