okie so first of all, THIS IS FREAKIN CUTE!! <3 ur new chibi style is adorable~ wants them for nendoroids lol
Vision: 5 stars cuz cuz its very pleasing in vision ;v;/ its very cute traditional drawing is so hard to make it looks clean tiny detail in background is so awesome! becuz i saw this in real life, i know doing such a detail in a small canvas size is hard. but still, you are able to do all those beautiful highlights, shade, etc also when people draw 2 people in the same drawing, they tend to look unbalanced like in height and stuff but this one, both of them look perfect ;v; not one of them have weird anatomy and proportion. its pretty hard to get those right u know?
Originality: 4 stars background. you usually just copy paste stuff from pixiv but this time you didnt ;u;/ also these are your original characters so for your creativity of making up your own character is d( =v= )b your way of drawing your name is pretty original too but yeah chibi style is soo common and very famous style people always draw. but your drawing style does not look like someone else's style or look like its a copy of someone so its still great! ;v;
Technique: 5 your techniques are just so pro~ your lineart are very clean which is very hard to do in traditional (well at least for me) the characters' expressions are so precious! it shows their characteristic really well. i especially like how eiji seems to be struggling with the winking. niya niya =v= also ai's pose and expression show her active, cute personality!
Impact: 3 and half impact is pretty much the overall of all those three above ne? this is just me but i feel impact in drawing when something aggressive or active things are going on or there are bunch of details in drawing or etc so this drawing, is not really WOW! AMAZING! AWESOME! ASDFGHJKL! compared to your previous drawings. of course this drawing is one of those "wow" drawing but im not saying this because i want to be mean and stuff. i tell you cuz i know you can do better! and im sure you know that right?
