One think I noted right away from the screenshots, is that it's well.. pretty.. small. And short. IT feels like that Sonic players will completely obliterate Tails and Knuckles players
And, believe me. Sonic will thok if he wants to, I know he will find a way, in this level. It's very hard to thok-proof a level with people nowadays. And even then, trying to completely prevent a character from doing their ability is poor level design in itself. And finally, it would be probably more interesting to have a more complex track to play through than an oval (Even race tracks in real life have plenty of variance.) And you could also give some nice scenery and variance for players to look at as they go through the level, so they know where they are and have something nice to see while they play.
Starposts: To set up starposts properly, you must give the first starpost an angle between 0-359 like usual. Except, for each next starpost in line, you add an extra 360 degrees. So, the first starpost will have like, 180, as an example, and then the next one will have 180 + 360 = 540, then the next will have 180 + 360 + 360 = 800, and so on. You can also look up on
http://wiki.srb2.org for plenty of tips in making your levels!
It's cool that you're trying to start making levels, though! It takes quite a bit of practice to get better in level design in general, and you made a really proud step by showing your work here. :)
