Respect! Your account seems new so I thought I'd send my regards. I just upvoted you for this as you deserved it and maybe upvote some of my stuff too!
I am struggeling, like you, to get those big upvotes on my posts so my advice would be to give @MinnowPowerUp a go as you can earn up to 30% more steem power than just powering up! It's a subscription based daily upvote bot that draws its power from a delegation pool. I have also made this post where I explain my experience with the service in more depth and show how I earn over $1 a day in upvotes.
