Grammatical errors aside, this was a great story. I really don't think there's much more to say, aside from 'great job'.

I'm gonna give this story a 9 on the itude meter! I hope that Sweetie has a great career.

I am glad this didn't finish with bad-endding like many stories involved with dark magic.

And that is the end! I hoped you enjoyed Envy is Magic!

Wait what?

No...

You can't be serious...

Why?

Why did you leave us there????

Interesting, no downsides to the spell from the evil spellbook. Also, where’s the big check for Twist, who made this all possible by sucking so bad that she was jealous of an unmodded Sweetie Belle.

Twist was just one of the catalysts and not essential enough to appear in the story a 3rd time after the spells been triggered enough.

I think Sweetie Belle should get her a really nice gift as thanks for being the catalyst.

I would love to see you continue this with little bits of her daily life being a muscular giantess.
This story was a lot of fun, I hope you do more growth stories in the future, you make them really fun.

Same here; there's not a lot of good macro and this is good.

Gonna assume "in the" is missing between those two words.
