Spoiler I know its simple, but I'm still just messing around with photoshop. I'll probably get around to reading some tutorials and stuff when I have more time.
I like the faint outline and the lens flare is a nice touch however your render could of been blended in alot more softly, right now it sort of sticks out like a sore thumb. Its pretty good for a first try though I assume you followed some sort of tutorial to get the effects it currently has. Keep it up and I'm sure they'll just keep getting better.
Actually other than watching a friend edit some pics, I had no prior experience in photoshop. I just kept trying different effects and stuff to see what I liked. If I liked it, it stayed, and if not I got rid of it. What do I do to make the render blend in better? It's actually a picture of me that I cut out of another pic, so I don't know if that affects anything.
