Interesting! You're doing fine, so honestly, just keep going.
One thing you should change is your comment in your description. When you copy paste "subscribe and find me here!" you're making yourself and your comic less personable! If people are interested, they'll sub ((this isn't youtube, where people need to be reminded, it's intuitive)). Use the description to say something you feel about the page, either in content, or the process of making it.
I don't mind the link to your DA as much, but rather than putting it in every update, think about just included it occasionally. "Oh hey, don't forget you guys can see more of my art here! -link-"
When you include the same information every post, readers will just start to tune it out. So by using it sparingly, you'll get a bigger burst of attention each time. It's the same with reminding people to tip or visit your patreon.
