Y'know, I thought that was a robotizier when the thumbnail loaded and was wondering what the heck Sonic was doing standing next to one that appeared to be activated =P
Hints--that Sonic is the ultimate? What kind of hints? I didn't really catch any, then again it's been a long time since I played the game in story-mode. I have my own loony theories about Sonic and Shadow that are somewhat related to that tho ;)
As far as the image itself, damn you are good at drawing backgrounds O.o I can't even draw a field of grass ^_^; The--er, what is that tube anyway? Whatever it is, it looks a little flat. I understand you trying to make it look as though it were glowing, but the inside is just so flat and unrealistic, the things hanging inside don't really help either as they add to the flatness. I'm not sure what you could do to fix that though since strong lightsources and the shading that goes around them isn't a strong point...
Sonic looks great BTW =) The only thing I see wrong with him is his arms are very uneven looking, and his nose seems a little off center.
OOoooo I realy like this one, the colouring on the tank thing is cool, nice light effects. overall an interesting idea.......goes off to play SA2
