If you want a piece of digital art to be interesting, you will not put lots of text. You won't even put a single paragraph. Maybe two sentences at the very most. Having so much text makes the piece boring, and if you use it to fill up space, makes you look like an amateur.
The entire stock looks like it was done in Paint in two, maybe three, minutes. Grab an image of Jack, reduce non-blues, put him on the left, make a textbox, and copy-paste a quote of Jack's. There are no effects to the piece at all, making it look unbearably plain.
There is nothing redeeming in this piece whatsoever.
Go follow some tutorials, it looks like you'll really be needing them if you want to keep producing digital 'art'.
