I already posted this in my gallery to show case my OC but just in case nobody seen it posted it here as well. 100% Custom.
Oh thank you so much for the compliment, my style is based off my own just carried over to Maplestory, mostly palette choices. Though there a tweak towards the difference so it feels like Maplestory mostly from the shine and slight brighter colors. I'm really glad you like the color choices!
I mean, on second glance it's really hard to tell the difference between the blue and the black on the jacket, I think your colour range is too narrow, maybe invest in the deeper and darker colours so you don't have to entail that much detail in order to make the blue pop out etc. Also, from my knowledge of MS sprites, I think you may have accidentally cut one pixel off the head's regular shape and added in a pixel elsewhere here:
The color choices are suppose to be like that due to my original style, It's suppose to be kept that way to show my style carried over. I've seen great MS Pixel Artist like @Paul and @Sai and they have their own custom style and this would be mine! :) Though ofc as an artist I have to be flexible to every style as long there is a mix of my own style, I wanted to stay true to Maplestory that's why the light source on the hair is much noticable, so when I make Maplestory sprites people will automatically know it's mine! :D Cause all it is my colors in my OWN STYLE carried over c: Oh 1 pixel off the head? No idea, If it's just one pixel I don't mind it as much xD.
