I have for a long time been a fan of your excellent vectoring skills, and this comic strip certainly dos not fail to impress.
This is very well made and so show-accurate that I think the producers would have difficulty telling the two apart.
I do not want to say that the vectoring is bad, because it certainly is not, but for the speech bubbles, I love how you did them the same colour as the pony who is speaking and also changed the font, but I think that the text could be made a little clearer is not stretched and it would be easier to tell which pony is speaking if you used something like a line or arrow to indicate which pony is speaking.
This is a completely original story, but as there is a TV show about MLP:FiM, I have had to take off one star. I am sorry, but something that has appeared on TV simply cannot be fully original.
But for any who just want a Derpy story, then this'll suit you just fine.
Your technique is almost fully flawless, only thing to note is not to stretch or squash the text.
This could have an impact on many who like Derpy and want her to have a new headcanon, but however, since I am not a fan of Derpy (but I do not have anything against her) I have taken .5 off.
I hope that you find this review a good summary of this piece of art , thank you for reading.
Luna: Perhaps it be a first draft, sent in err?
Do not fuck with the motherly, menopausal mailmare
Dear Princess Celestia,
I am writing to you today about an urgent matter: I THINK DERPY HAS CAPTURED SPECIAL DELIVERY, OUR NEW MAILPONY CARRIER! PLEASE SEND THE ROYAL GUARDS TO INVESTIGATE THIS! WHO KNOWS WHAT SHE'LL DO TO HIM!
Princess Twilight Sparkle.
Looks like Derpy got tired of waiting for the Postal Union's decision on the matter, and took matters into her own hooves.
Ironically they made it even worse, by saying that being abnormal is bad.
I can imagine the letter Twilight was thinking about would say:
"Dear Princess Celestia,
Derpy kidnapped Special Delivery and has become the new mail pony. Send in the Royal Guards ASAP!
Your faithful student,
