Welcome to DA! You've already uploaded some amazing works, really nice style you have. I've been around for six years now so if you have any questions don't hesitate to ask
I leave here some suggestions on things you should do:
Forum: another easy way to share your work! It's really intuitive and it has helped me to discover amazing artists.
Groups: I see you are member of one group. I think being in a group is the best way to show your work to others and meet some great artists. I encourage you to visit this:
ProjectComment group. It's designed to bring quality feedback to the artists and the admins couldn't do a better job, it's full of interesting activities and lovely people.
Llamas: I'm leaving one for you, just because they're awesome.
And if you want to know even more about this site you should read this amazing

That's it, but you can ask me anything. Enjoy your time here!
