I really like this piece! This is an amazing idea with quite an excellent execution. The scene is amazing - everyone is completely in character and there are so many nice little details, from the pieces of food flying to the frosting coating Pinkie's mouth.



You have a unique style for the pony faces in this piece which is quite pleasing to look at. This style gives the ponies a significant snout yet retains an excellent portrayal of emotions. Pinkie Pie looks so pleased - the expression is perfect, from Pinkie's eyebrows to her mouth. The cheek bulges add a huge amount to her cheer and personality. Similarly, Rarity, Applejack, and Rainbow Dash all look amazing. I don't think this style works quite as well for front-on views - Fluttershy looks a bit off. Her eyes are great - really nice shading on all the eyes - but the shape of the chin doesn't sit right with me - it doesn't look elongated, unlike the other ponies. Perhaps a small line above the nostrils would help? I also think Twilight's far eye is a little to high on her face, giving her a little bit of an odd appearance.



The shading is quite good, and adds a lot to the piece. It is consistent everywhere, if simple. You've given it quite a bit of thought, with the ponies casting shadows on the table, the folds in the tablecloth, and Rarity's handkerchief. I also really love the highlights in the hair, which gives life to their manes, Pinkie's especially.



The background is nice, simple, out of focus to preserve the focus on the mane 6. The table has a lot of detail, but is important to the piece, and unifies all the ponies. The little touches are all amazing, from the food flecks, to the leaves on the table, to the book Twilight decided to bring (though it probably needs some magic too keep it there).



I see you've been playing around a lot with different styles - continue to do so! It can be quite fun to change things up. However, I for one would enjoy seeing more art in this style of pony.
