>>2094393>>2094394First off, if you're going to post vectors here and ask for feedback, post the transparents without your gradient backgrounds because those are much easier to work with.
Second, you are using WAY too many nodes; your lines look super choppy and lumpy, almost like you're using an automatic-vector website / plugin.
Third, you've got serious line consistency issues, your lines are getting super thin and thick for no artistic reason and it looks bad. See attached image for example.
You really need to watch and follow the tutorials in OP, daul is very good at this and did a great job explaining how and why to do things.
