Hi friend.
I think your drawing is very nice.
I think that there will be a lot of worries about how to increase followers by now.
In my experience, I think it will be most effective to visit the other person's blog and comment.
There are many artists here, and some of them are interested in your drawing.
And even as followers grow, they do not always vote for you.
The amount of power they can use per day is fixed.
So do not be disappointed that your followers do not come back often and hope you enjoy your adventure with patience.
