Everybody has to start somewhere. You like superheroes so why not? It's an excellent way to start. Yes I think they are good. You will learn a lot more. I like special effects in banners. It's fun to play with several tools.
I'm still learning. My dad has been helping me. If I want to do something and don't know how I just ask him. It's nice to have my own private tutor. :}
i really like the first susan one.
you are getting better.
we all start off kind of rocky and then improve, you wont be any different. it only gets better from here.
The best way to learn things quick is to follow the tutorials you want. I started with nothing. I could only blend two pics but not without making a mess out of it. Then I followed tuts on the web and learned how to use many tools.
Is your father known with graphics and how to make them?
