For someone who seems to be new to graphics, this is very well done. I know for sure my first graphics looked 100 times worse than this! For the jersey swap, you did a really good job! One thing I would note is that maybe in the future, take the couple of minutes to stamp over those alternate shoulder logos. Especially if you're applying a filter like you have here, they can look pretty sloppy and you can still get away for it. The gradient on the text could have been a bit less strong, it looks slightly unappealing. Honestly though, for someone's first graphic, I would give you a 8.5/10. Well done!
