freedom of speech is fine
don't take a comment like that personally
i much better way of saying you don't like someones work is something like
"you could improve, followed by some things that could be improved"
also if you plan to become an artist you will have to get over people being critical
its totally an opinion

i personally don't like the pic, too anime for me
but i am clearly not the target audience
so i gave you some tips i thought would help


one last tip the fastest picture i have ever made that i was happy with took me 5 days of hard work.
art is not something you can get good at quick
"if someone is way better at art than you this is not some innate talent,
its because they love it more than you and practice more often"
practice is the only way to get good at art
