Beautiful tileset, and WOW what an upgrade over the original.

The purple in this is wonderful.

Don't get me wrong, I think it looks great! AM2R was pretty derivative/conservative when it came to its tileset and Samus sprites, whereas here you have something which is a lot more you, and I would say a lot nicer than the custom work (especially the backgrounds) put into AM2R.

Thank you! I was very lazy to build Samus from scratch and I did not want let this piece  out withouth samus. Yeah I can see why its reminds ARM2 because it has multilayered cave backgrounds. I should have been maybe little more creative. 

I love this! Reminds me of AM2R, but very much in your style
The Samus's shape is very much the same as in your ref sheet, but I can see that you have reworked a fair amount of the clusters and palette of course - so much as I would consider the sprite an edit, I would say this passes as per submission rule 1.
Also, I really like the particles above the lava - I can just imagine it in motion and the lava glowing. Great stuff
