Grass with style from New Super Mario Bros. Wii Give me a credit if you use it
While a solid attempt, I'll have to reject it's graphic due to some lacking of shading and resemblance to the original graphic.
First thing, the shading is almost non-existant. The original grassland from New Super Bros. Wii has some shading in the grass and in the dirt part. This graphic lacks the shading of the original, making it look flat. The top grass part is also a simple edit of the original SMW grass and as per rules, simple edits are not allowed, unless they have utility.
Second, the flowers need a lot more of work. Their shape and shading doesn't feel close to the original and lack the proper shading. I suggest looking more closely to the original material and redo this tileset. Try to tinker more with shading and more colors.
