Um, I'm new at this Critiquing thing, so I'll write it plain and sweet. Sorry...
Vision :: Amazing pose, presents the request in my opinon perfectly! I can tell she's having the time of her life partying it up with her bff's.
Originality :: I've always loved your style and if someone asked "Would you watch My Little Humans done in thelivingmachine02's style" I would say HECK YES, because I love your style and it works perfectly with these girls.
Technique : Now, since this is a full Critique, I can not pretend that your background isn't much lower res then Twilight herself, I can say that it doesn't matter because it's not the main point, but this is a critique so it must be said. That being said...that is the only thing wrong with the actually image. Twilight doesn't have color out of lines, and looks really amazing herself!
Impact :: I wasn't quite sure how to write this, but I guess They mean Impact as in, did I laugh, or did it make me happy... Did it do something awesome inside of me or whatever.... YEAH, I was like "HEY, I wanted to go to Twilight's My Little Human Party!!!! NO FAIR" xD I really like your stuff! It usually impacts me because of your unique cartoon style and your ability to make scenes like this almost look like screenshot for the show I can only dream of.
Your art style has always been very intriguing to me--Your lines are usually quite clean and concise, and your colours are bright and beautiful, while avoiding too much saturation.
There are only a couple areas where I feel that this work falls short. The first is some of the lines (albeit very few) overextend or don't fully connect with their neighbors. These can be found in various parts of the hair (particularly at corners) and in the hands. This is an extremely minor detail and is only noticeable when exercising levels of scrutiny unheard of by most community members, critics and casual visitors alike. Secondly, though I recognize it as a part of your style, I feel that the lack of any form of shading really takes away from the piece. Even some extremely simple shading could do wonders to help this piece really pop out!
That being said, I'm a tad envious of your work. Your proportions are flawless and your facial expressions are always spot-on (not to mention hilarious and cute). Your style is your own, and it never ceases to amaze.
