>>1398031I think you're right with the gradient issue. I'd probably just leave it as it is. It looks fine like that.
A few more things. Nothing big, just stuff you should be able to clear up in a few minutes.
1- Her nose is clipping over into her hair. Move that node back so it's hidden in the hair.
2- It looks like you used two bezier curves to do this part of the hair. Either delete that node in the middle so it's all a single stroke, or make the handles from that node parallel to each other so that whole lock of hair looks like one uniform curve.
3- If you're going to add that middle part in the scar, try and make the whole thing flow, instead of making it look less tacked on. You want the whole thing to start thick, and steadily get thinner until you get to the end. I just did a quick little thing to show this.
4- More shadows overstepping their boundaries.
5- I can see a bit of light grey where there shouldn't be. Just drag the handles a bit to fix that. I like this shadow change. That part of the hair looks much better.
6- This is just like number 2. Make sure all your curves flow nicely.
7- I think I can see a bit of light grey there. Not really sure, but give it a once over.
8- I don't think this black line quite connects. Just drag it up a bit.
9- This tapers, then thickens. You want a nice uniform curve to a point, so adjust your handles, and move the node down a bit and end the line earlier.
Could you export a larger version of this? I'd gladly look over it closely to see if there's anything I would fix. It's looking a lot better now. You're pretty close to being done. I also like the eyes on this one better. Good job with those.
