Hello,
I'm an Italian artist and I'm interested in this job. I love to focus on new visual stiles and space between different types.
From the references, I see that you search big sprites, fully animated. A sort of "Another World" in pixelart with more details.
I'm preparing a visual sample, but in the meanwhile i have selected some of my graphic that could fits your idea.
These are sprites for a side scrolling action game. The game style is focused on Flat colors in an undead land, so the colors are pale. The sprites are linear, yet caraterized with details, since every character have his own personal story.
About animations and more bright colors, i can post you a sample of both from another game i worked for.
This is my full portfolio:
