So, I finally took my time to write a critique of this deviation. It has been about time. Now, you have probably checked my star rating and wonder why is that. I told you I don't go easy on artists.
Now, a warning before you start: I want to warn you, that at first it will probably seem to you like a really negative critique, but that's due to the nature of this deviation. Don't be scared! Now, brace yourself...
I like your vision of Arcade Sona. Generally, I find it hard to think of any better Anime adaption of this particular LoL champion. She has all and every feature of the Sona we know, and it's a mere 'remix' of the champion. Admittedly, maybe I would have hoped to put a slight extra twist to it. Don't get me wrong: I think it's marvelous. But I think you can do better. That's why you get 4 stars out of 5 for the Vision.
Well... everyone who ever played Sona know the champion. Most of them also know there's the Arcade Sona version of it. So, anything more than 2 stars out of 5 would be close to an insult to the artists (or artwork) who make their own creatures, characters and even worlds. I know you are perfectly capable of making such things - you did it before - but this particular piece is not one. That's why I'll save other three stars for your future artwork.
You absolutely rock your technique. Years of artistic expressioning is shining through every pixel of this drawing and soon the world might have to add additional colour to the palette so you can use it. Clear 5 out of 5 stars for it and I don't have second thoughts. The execution is flawless. Once again, I trust you will only get better, but I simply have no complaints.
It's Arcade Sona. We know that. It's probably just another Arcade Sona. I pointed this out in Originality and therefore I'd bet my tomorrow's lunch money it won't have any noticable impact on future art - either your own or anyone else's. It just might be the nicest anime/manga-ish Arcade Sona drawing out there. So that kind of seals it. You are capable of pushing the boundaries, you will, but not with this deviation. It was a great way to practice your skills, and plenty of fans will add it to their favourites. However, it will mostly be due to the fact that they love LoL and Manga art, but not because they would find this as something entirely new.
Now, until here, it probably sounds like I destroyed your artwork. I only favoured your exceptionally good execution, but let's distance for a moment. It's actually also the only thing that really really stands out. We just learned, that skill is important to please the eye, but the soul remains unsatisfied. So once again, I have to absolutely congratulate you on your skills, but I'm infinitely eager to see you make a really original deviation. Deviation is absolutely an eye candy, and I know it is precisely what it's meant to be. From that point of view, you would get 10 out of 10 (hey, that's what 5 stars for the Technique is, right?), but that's just one aspect.
I look forward to see more from you. Don't get scared, I encourage you to make more of fan-art and re-interpretations like this. But then, I'm sure your imagination has so much more to offer us. And that's what I really want to see from you.
So, that's it. I hope you didn't lose trust and excitement in what you do. I know I'm not much of an artist myself, hell, even I did many remixes of LoL champions, although it's set in a little bit of a different setting. I kind of took the "mentorship wannabe" route in this critique. Of course, I pulled this off, because I plan to get out of you more than you expect from yourself. You are a really good artist, but I think you can also be an outstanding creator - if you know what I mean to say. Now I'd like you to remain critical to my critique, and think for yourself if you disagree with anything what I said. In the end, I just may be wrong at some points.
