Here is the final piece. I've been working on this for about a month on and off. It was going to be submitted to the Sonic-club contest but I didn’t have the time to finish it until now.
So I guess this will only serve its original purpose. This is a tribute to Raf *digital-addict His work has been a great source inspiration for me ever since I got started with my own. So I felt I owed him something. Thanks a lot man. *bows respectfully*

Description:
As you can see, I tried to capture his drawing style and cell/soft shading technique that he did in his “Bright and Shiny Future” comic. The robot designs as well as the outfit of Sonic were directly from his design.
Tails and knuckles were designed by me. I tried to imagine if they were in the comic and I came out with those outfits.
Knuckles is wearing green and brown. He wears a shard of the master emerald around his neck and his trademark digging gloves.
Tails is wearing yellow and dark blue. I tried to have him fit his tornado 2 color scheme. Oh and yes, he is wielding a blaster pistol. XD I took the weapon from the “Sonic Battle” game and revamped it a bit. ^^
Overall I think this gives a nice futuristic/urban/rave look that fits the comics. ^^

I wonder how this would have fared if it was submitted into the contest... XD

This picture had a lot of detail packed into it. Just showing this would not do it justice so I decided to make three detailed pics from it:

Sonic
Tails
Knuckles

Anyway, I hope you enjoy it as much as I did making it!
