Wait so the player is Luigi? I noticed that on the HUD.
EDIT: lol nevermind I read the post again
That grass and wall texture looks amazing. It's very realistic if you look near the far wall by the goomba. Looks like you changed the model for Mario as well instead of just changing the color of his clothes like people on youtube do.
The tree's wood texture is custom by mushing and warping a square with a light brown and white color( In Paint.Net), the wall and grass texture is from yoshi's island on SSBM/SSBB, the soil is from SMG2 and the water is from MKDD.
These pictures look really good. I like the choice of textures. But there are two (minor) things which look weird on the second picture. The windows look strange and the peach picture too. But other than that, great job!
Currently working on my Title Screen, just came to my mind when I was making one for a hack but then I just jumped into this, will improve it once I'm done with increasing the brightness of Flame's model, I'm currently checking the 0x03 and increasing the integers at the end, will take loads of time.
This is the Screenshot of it in-game though.
