Howdy! Your account seems new so I am offering you my welcome. You get an upvote and full steem ahead!
I am struggeling, like you, to get those big upvotes on my posts so you should try out @MinnowPowerUp where you can earn up to 30% more steem power than just powering up through steemit! 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.
