Yoyoyo! I looked at your profile and noticed that you have made a fresh account so I thought I'd send my regards. Have one upvote on the house and rock on!
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.
