I did this out of boredom, and plus the current one is very unoriginal and won't get as much reads as Sophie Potter. Did you know more than half of wattpad click a book for it's cover?
It's not like someone could look at the cover of your book that has 4.2k reads, and say your summary was what got them to click the book in the first place. Not saying that you should improve it, but that's would be nice.
Oh wait, off topic.
Presenting TNSM's Second Bookcover :D (TNSm = The Not So Muggles)

But the flaws that I noticed after finishing were that it may be a little too detailed, and there is only one girl, and she does not look blonde. Soz.
And that the witch hat was super obviously placed by me.
AND I was unsure of her eye colour, otherwise I would've gone over the eye like I did with Sophie Potter's. No? No one noticed the awkwardly coloured 'bright' blue eye yet?
