When it comes to Metroid fan sites Shinesparkers is one of the coolest around, I highly suggest you to check it out! You'll find lots of very interesting and informative articles about the series and interviews with actual pr0s who worked with Nintendo on Metroid games.
They recently started a Community Spotlight, where some very talented Metroid fans get the chance to share their fantastic work and get some recognition. For some weird reason they asked ME if I was interested in getting one!
If you're curious, here's the Shinesparkers home page: https://shinesparkers.net/
