Try not putting filters on your render. You dont want your render to look LQ. Also theres a random dark spot to the right of the render, like a line or w.e., looks like you erased some stuff. Try to fix that. Text is a little bit hard to read because of the font, and the placement+color should be changed a bit. Also, try not to sharpen too much. Usually you want to blur the background to give it depth. Lastly I would say work on your lighting.
