Chapter 3: Hello. I'm also a graphic designer and I thought I could give you some tips that worked for me while I was creating posters and the such. I hope you won't mind too much. :-)

First of all, I learned that layering textures over the focus is not a good idea as it takes away from the edit. For example, I try to erase all stocks and textures that are covering someone's face. This is a method that JackHarries taught me, and it really does make the poster both brighter and clearer.

Another thing I always do is erase hard edges of an image with a low opacity brush. This makes everything look more "connected" -- if you will.

And then I save my images -- and export them, because I use GIMP -- with the extension .png. If you use .png rather than .jpg, your edit's size will not be compressed or decreased, if I'm not mistaken.

Hopefully, I was able to help you. You're doing great, however! I'm sure you'll be able to become a great designer. :-)
