Sonic Form Sprites: Canon and Fanon

Please Note: I'm aware these concepts have been done to death, and that they really aren't inspired or original in any way. This was done both as a practice project and to show my interpretations of fan-made Sonic the Hedgehog forms. Also remember that these were made with my own sprites and I what I choose to do with them is my business.No edits; from scratch content

I really wish I didn't feel the need to have that whenever I do Crossover-inspired stuff; I know it comes of as bitchy and whatnot and I do apologize for that.

Anyway:

I wanted to practice spriting Sonic forms I didn't have much experience and show some design concepts of my own. I will admit that Spectra Sonic turned out an absolute mess here; but, unfortunately, I feel that's the best I can do for the moment(I'm going to have a whole journal on the subject as to why that is).

The Forms:

Row 1 (Canon)- Normal, Super, Hyper, Dark/Dark Super, Darkspine, Werehog, and Excalibur

Row 2 (DBZ inspired)- False Super, SSj 3/Turbo, True Hyper, SSj 4/Feral, SSG/Mobian Legend, SSGSS/Ascended, and Alts.

Row 3 (Other inspiration)- Rainbow Power/Spectra, Captain Mobius, and Captain Mobius (without spring-shield)

Opinions (if constructive) would be greatly appreciated on the sprites. I've never done some of these forms before; and I'd really like to know how I could improve my methods of depicting them. Again, I had a LOT of trouble with Spectra Sonic, and I may even update this to include a more well-polished version at some point.
