You know, I usually hate to see motivational posters with images taken from the internet... but this is actually pretty creative, and there's a point to it, so kudos to you for not making me want to reach for the report button.
thanks I dont find anything bad at it, and I would really like that you explain your point to me, as I will explain mine to you: I'm not using this images to obtain any profit. The only profit I gain with this, is making people laugh.
It's more that people often post stuff from the internet on DA, and DA's submission policies are that you should only post artwork that belongs to you. I usually leave memes alone but I see a lot of motivational posters that have images from other artists or taken from the internet, and some people just post stuff they've googled. Whether you make profit or not, it's still against the submission agreement since when you post you claim that you own the picture.
In this case I'd say you've been creative with the content though, it isn't just lifted from somewhere, but put together in a way that has some meaning, and with images that are considered pretty much free for use to anyone, although in the past there have been disputes regarding some meme images, like the philosophy raptor.
