If you consider working on the hive blockchain as a "work of freelancing", then I should say that your are doing pretty well. You have built up a network already and it is paying off. Keep doing.
However, to be more successful as a freelancer, in this era, having a skill in two things is very important. And you have already mentioned them; graphics design and coding. You can try to learn them as well. It will boost up your status as a freelancer.
Good luck and wonderful day.
