Yoyoyo! I saw that you joined recently so I'm sending you my support. Have one upvote on the house 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 more info on my experience with the system in this post where I explain how I earn over $1 a day from upvotes.
