They are looking good mate, keep up the good work. Definitely a lot better than what I made when I was starting out with Photoshop.
For me, the text just doesn't quite look right. When you're reasonably new to graphics, plain basic text always works the best. Even something like Times New Roman can work well and effectively. Fancy writing on signatures often ruins it - simple is better.
Some things you might want to try with your text that I did for most of my graphics - make the first name smaller and in lower case, and then create a new text box, make it in upper case and bigger and put the last name there. You can fiddle around with the move tool to get the text working nicely. You can also fiddle around with the opacity, and if you wish - sometimes making font 72 text and setting it to overlay doesn't look too shocking if you position it right.
There are quite a few simple things you can do to help your render blend in better. You've probably already heard of this but it's what I consistently use - simply duplicating the render (the main player) and then using the filter effect Blur > Gaussian Blur at 4 pixels. Then, simply move the blurred layer underneath the main one to create a simple little glow.
There is another way to do it as well, although a bit trickier, but it helps it blend in a lot better. Select the lasso tool, and draw a little circle next to the player's arm or something similar.
Example:
Then, hit right click > Feather, set it to 5-10 pixels (5 will get a more thorough blend whilst 10 is quicker) and then just keep hitting delete until you have it how you want.
Also, try to stay out of logos when you are new to graphics, it's not always the best idea.
Other than that, keep up the great work, hopefully you learned something from this.
