Well... This really requires two different critiques. one from an artistic medium, and one from a functional medium.
From the artistic point, I love this to death. The vectors are nice, and chrome symbol is great and within the vectors I couldn't really find much to complain about.
Unfortunately, as they are vectors, done by others, I can't really say I appreciate them as your work. I know you did a lot to get this done, but something is just taken away for me when I see that the work isn't 100% the posters.
Now I'm not attacking you here, you have great vision, and with continued practice, you'll not even need another persons vectors one day. For now, you're pretty damn good.
From a functionality standpoint, I have to say that it's actually quite nice. You keep the original style, and still change it up to be something fresh, interesting and recognisable. Also, I don't see this clashing with most desktop schemes, good job!
All in all, I really do love this, but I want to see more work that is just YOU. Again, not attacking you, no matter how much it sounds like I am, but you gotta do the hard yards too if you wanna be high up there.
i Love this alot! its good, and you just won me over with my two favorite non-princess ponies ever! its good, nice HD with the chrome sign, and it just wows me! i say, what are your ideas on more? (personally, id like a Luna and rarity one..) jsut me though... anyways, once agian, nice and keep up the goodness! this is waay 20% cooler than me. ^^ well, i may say that its good, and you used alot of HD and the sign stands out to me the most, and the ponies make it Special so good work my friend
I just realized that Sunset Shimmer cutie mark is a Sun and Trixie Cutie mark is a Moon and Celestia cutie mark is also a Sun and Luna cutie mark is also a Moon, they both (Sunset and Trixie) used to hate Twilight and reformed by her and they both have talents in Magics.
