You need to work on adding some effects, also I would suggest having no font or practicing more with fonts and colours because that font is way too big and the colours don't match. You should check some tutorials out in the tutorials section.
Thank you for your comment. Though, i think i did a good job on the text. That's just the style i like. I was intending to keep it clean, but perhaps you are right and perhaps i should add a fancy sattleite or something like that.
i dont like the blurr on the spaceman, i think maybe use the spaceman as the main focal (sharpen) and blur the BG, just my thoughts
