contrast is way low and its not shaded really and has banding all over.
Hasty edit as I'm really meant to be working:
Notes drawn on yours, the boobs and cloth in mine (not to mention arm & forehead) are still shaded jankily.
The banding everywhere and the colours are the main thing, everything else is a lack of construction and practice I'd say.
Ok, I'm back again... Thanks to above person's visual example I took my god-awful first picture and tried remaking from scratch... Ended up with this.
And up closer.
Ok, well, you don't have to tell me the new version is also bad... But I'm hoping people think it's, at least, an improvement? I originally didn't have the dark edges on the shirt in the new picture but threw them in and forgot to remove it again, it looks better without them. Also hastily edited in a necklace purely because she had one in the very first picture - If I keep the image it'll be removed, she looks better without it, it's too formal looking despite her wearing a casual top.
I loved what Geti did with the T-Shirt/Top she's wearing but wasn't keen on the sporadic looking skin (Facially), it seemed way to complicated for me as a beginner - Also I know the shading etc is still pretty bad and I didn't really get to do much with the hair (And also still a bit disappointed with the face, finding it hard to get it as detailed as I would like, but at least it looks somewhat human when the picture is viewed at it's regular size) but again, I hope people think this is a better attempt.
Further help with tips or ideas for improvement welcome. And no, I will not ask people to do their own edit for me, although a visual example of what can be improved is much easier to understand rather than saying it outright seeing as I haven't even got a clue what things like banding, jankily etc even mean ^^
If I can finally complete an acceptable and satisfactory final picture, my next step of learning will be to add a few easy frames of animation to it just to see what it'd look like in motion, probably something simple like blinking, or have her turn her face towards the camera like in the quoted picture. One way or another I will get better and finish drawing this woman, damnit!
Wish me luck.
