Hey ho nice sketchbook! really cool entries and I especially like the landscapes
but a little advice on the latest artwork try to use a bit more hard edges (if its called like that)
because it looks a bit to soft/blurry (i do not know the right term for it)
You have improved your skin rendering on the last portrait, nice
values and nice blending. The eyes however are a few steps back considering
the reality grade, it’s somehow too cartoony compared to the rest of the face and
hair. Also the mouth should require a bit of shadows and blending to look more
like the part of the face and not floating over it. I suggest you to do some more
eye paintings, copy them from photo references, try to get the right colors, right
shapes and right highlights. As twelvex mentioned above, you could have used
some sharp edges, for example under the chin and on the right side of the face
where it meets the hair. I see some very interesting paintings above also, you
have been working hard and I think that there are definite improvements.
The diligent dedication pays off in the end, I respect everything you do,
and I think that with this pace you will be even better in no time.
So keep up with the good things and don’t give up painting.
