- generally hair is more pointy, unless you're going for a certain style, but then you gotta keep it consistent throughout
- use less nodes wherever you can, and if possible, only one of the handles to make a curve between two points
- the tools are there to ease your life - again, unless you're going for a rough or wobbly or some other style, things like cigarettes and "produced" items in an image are usually of smooth shapes
- the circled bits are a seemingly out of place transparent hole, the other is the finger is really thin compared to the others
this now delves more into my personal opinion and it might be my eyes or monitor, but the bottle and the filter seem to blend in with the pants / skin, and the blue eye feels a bit too blue, but take my feedback on colour with a grain of salt
And I have this collection of other advice and examples given out over time
