Pretty interesting you're inspired by hyper light drifter, with its high contrast neon palettes when yours are so flat and grey. When you don't have any shading or outline separating your forms, you might have to push the contrast a bit. (Yeah, it does look better in motion, especially with the relatively high frame rate but it certainly can't hurt).
Besides that, the pose looks pretty weird. His legs look small, his body looks long and leaning back, and he has no neck. It's pretty confusing to look at - the highest contrast on the sprite is the least important detail. I would drop that diagonal belt thing all together, but maybe make it 2px wide and dark green otherwise.
It's also a lot smaller than the original sprite.
I really love the original artwork for Zelda 2, maybe you can take more from it?
