This Sonic X Trip Neo Geo Games?

Damn, this is one fantastic sheet. Nothing else to say but damn.

@Sneakyslycooper It's more like it's own style that's influenced by all the games.

I think these might be Advance style.

can you do sonic and his friends?

This is fantastic! Except... I have a few questions.
1) What exactly is this style? It uses way too many colors for the Genesis style. It reminds me of Cylent Nite's work, but his sheets were always lacking the full animation sets required for implementing in a Sonic fangame. More info on the style would be helpful for people wanting to make badniks/players/bosses/stages that will pair up with these correctly.
2) How do you assemble some of these things? I have no idea how the springs go together. And what's that weird machine next to the half-bumpers? Took me some time, but now I recognize it as the shoe spring gimmick machine from Sonic Chaos.
3) How do you properly warp the image to use with the spinning item cards/goal sign??

I...I think I came...

This actually goes well with Clyent Nite's work, nice!

This is very impressive! It has stunning quality too, it looks pretty official!

These are great sprites! Are there objects from every main Sonic game?

Holi crap, outstanding sprite work!

All of this is really nicely done, and the amount of assets included in this sprite sheet is really amazing.
