Its all relative.
In one hand; if you think its good, then its good (if you are satisfied/pleased with your work of art)
and that's what really matters. (without fearing being too self centered)
In the other hand; if you want/need acceptance of others to feel good of yourself
and your work of art, you have to accept criticism too, without exceptions,
because that's one possible way to improve/grow yourself.
(even if you would be looking for positive note or support and such)
What comes to your question; what do you/i think?
and for my answer (what would actually truly matter,
more understood version rather)
A: You can always do better and that's a good thing
(even when you are pleased to your work, it's
more gratifying when you improve your skill)
PS. I hope my response made any sense at all :)
