Mario's Pad?

[PintaT]

I am currently in the process of making a new SMBX episode in which Mario/Luigi start in their house and try to save the princess from the baddy by going through a strange new land. For this, I need a custom graphic of the outside of Mario's Pad as a BGO, SMB3 styled to replace the big SMB1 Castle (I believe that it is background_17.gif). For example, Mario's pad from Paper Mario for the Nintendo 64.

If anyone be so kind to help me with this. I do not have much experience with pixel art so this is all new to me.

Thanks a ton,
