Not gonna lie, I absolutely love the head, a unique hair style I never seen before. In my opinion the back of the head looks nice which is kinda rare in graal graphics because usually the heads at the back usually 90% of the time are plain. Love the head, The art style also reminds me kinda of Coco and dusty a bit but is also kinda unique on its own really.
And also the brick tiles are also kinda neat, I kinda like the shading and color. Reminds me of a pyramid. However the only problem I can really see is the bricks at the bottom look more ...pointy at the corners while at the top it is kinda clear you removed a pixel from the corners which kinda gave it that nice round clean corner look. And also the bricks don't seem to make sense kinda how they are laid out and how the small bricks kinda don't size up right getting bigger to the top. They all look same size, Which still works, other than that I personally like the light amount of shading,
You have some really impressive graphics, Can't wait to see more from you !
