The REAL Yoshi Island...
This would have to be one of the most amazing pieces of Mario-related art I have ever seen. I am a big fan of realistic renditions of the Nintendo universe, purely because it takes things in a new and interesting direction, and this is definitely no exception. I originally saw this piece in an art contest thread, and it reminded me a little of José Emroca Flores' work on The MK (which I have always regarded as my absolute favourite example of mario 'fan art' and is an image which spent large amounts of time set as my desktop wallpaper).
The clincher for me though, is that Yoshi and Shyguy are two of my all time favourite Marioverse creations. To see them after your treatment was awesome.
Nailed it.
