i love the idea however i have 4 problems with it.
-The head is a little large for the style you're using
-The nose is being shown at an angle when the face is facing forward
-Highlights are used on the glasses however not on the eyes or hair
-Art is a little 2D-ish, there really wasn't that much depth to the head
Now lets address these points of criticism individually shall we?
Now with all faces in an anime style the faces are always defined by their hair, the hair on this is very thin cut and isn't really true to the anime form or realist form for that matter, the hair was not thick enough really and a little spiky, i mean that's a little what the anime style is all about however you were doing a self portrait of yourself so i think it should have been more referential of your own hair than this stylized approach.
This was the thing that I immediately noticed from the thumbnail.
Perception of an object should always be considered when drawing its what separates the artists from the doodlists, and can define you greatly as either good or bad, my advice for this is to look at your nose from head on, i know you may be thinking that that's what all the anime artists do but that's a misconception of design that goes into anime, besides why are you limiting yourself to the style of anime?
Highlights if you don't know are patches of light so potent that they turn up white, to know how to do this basically imagine a light pointing at your character/self and imagine where the reflection points are, you should probably practice this, its quite tricky and some of the best web comic artists i know still haven't come to grips with it yet.
SHADING ME LAD, yes that's all you need, and this shading needs to be really potent , i see you've gotten to grips with shading in some parts though if i were you id go alot thurther to better define certain areas and kind ago over it in something and plot out the shape of the face where it dips and curves is a good idea.
its an alright idea i might just steal the step by step gif idea, the art however needs a little more work but not at all is it terrible or unbearable, you show alot of potential and you just need to develop more of these 'artist senses' to get good witch i know you can do.
- perception of an object and or person
- Lighting and Highlights
P.s. I got a really big vibe of Love Hina from this..................ever read the manga?
