I think you could make it better by giving a splash of softer (or darker) filter so that the color will be, uhm, friendlier? And j-hope's pic will be more awesome if it's in a high quality one.
The font color for the title will be nicer if you give darker color, i guess?
Keep up the good work tho, i know it's pretty hard to start again after being away from graphic editing ^^

I like the dark writing on this poster and I like J-Hope's pic in the earlier one!
