You put a lot of work into this and it shines through! There were very few grammatical errors and it was structured well. As far as the content goes, I was most interested in the stage striking section and found that you were able to sum up Sonic's effectiveness on each stage clearly and concisely. Personally, I'd have liked to see some analysis into playing neutral game against top tier characters/his poor matchups but as you said you ran out of time and that's understandable. I could have given it four stars because of this but it was definitely better than "good."
I look forward to seeing you some more around the Sonic boards! Good luck and great job!
