>>1971038The advice I can give to you is...
Sometimes you need to think about how you can make the lines attractive, rather than keeping them exact to the reference.
If you always try to be 100% true to the reference you can run into issues where you lines can be awkward, and may come out unattractive to others.
Also, learn how to correct parts that might be pointy, look uneven or just don't flow well, pic related.
I won't point out to you all of the little bits that I can see that I would improve, because you need to be able to find those yourself. :)
