I would like to start this critique by citing one of the greatest philosophers – Lucius Annaeus Seneca, – who lived circa 4 BC – AD 65. He once said: "All art is an imitation of nature." Well buck you, old fart! I dare you to show me THIS THING happening in the nature!
Firstly I must admit that your work, Mr. Engrishman is one of a kind. Every one of them is one of a kind. Take me to the Court and I will say it again with the Pony Bible in my hooves – your art is amazing!
Just look at the sheer amount of memes that are neatly compiled in this piece: The infamous Trollface; Warhammer 40k Dreadnought-alike looking bulldozer, that also kind of reminds me of that dozer from that crazy Japanese fighting game where that guy stopped time and threw a dozer at the other guy; sweet Team Fortress 2 reference, hilariously crazy derped eyes... I could continue, but I won't. But I could!
The second thing that caught my eye is, of course, brilliant shading and quite a thorough work on every detail in this picture. Not a single part of this piece look rushed – just look at those weapons lovingly strapped to Twilight's hooves and light reflecting from Trollface's eyes! The joy and awesomeness your picture emanates one could cut with a knife! Little fillies, don’t try that at home – you could hurt yourself and cry, but nopony will hear you over the sound of how awesome this piece is!
And to conclude my critique, I would like to once again cite Mr. Oldfart Mc. Fartingtong (Seneca). He once had nothing better to do than say: "Be not too hasty either with praise or blame; speak always as though you were giving evidence before the judgement-seat of the Gods."
You know what, challenge accepted, bro! As Celestia’s my witness - I bucking love Engrishman’s art in general, and this piece I adore so much I am totally going to frame it and put on a wall in my bucking campus for everypony to see! You are doing God's job, Sir Engrishman! Cheers, mate!
