Very nice one. The colors and dithering has a certain early Irem style to it.
I agree, especially about the dithering! I think the color count and the outlines aren't big problems in comparison to this one. But it would be even better without these issues, of course.
Nevertheless, I love the colors and the design!
Looks great, but I think there is room for improvement.
The use of outlines is inconsistent, and probably too heavy.
I love the color atmosphere, but there are just too many colors (79!).
Too much dithering too, instead of better detailing and texturing.
You might find this old thread useful.
Вау, мега работа!
