here comes the fun part
.... where you'll apply your creativity
we'll start by adding the background....
1. decide how big the background will be, in my case, I want it to be 100 pixels high, and that the curvature in Dart's wings becomes the rightmost border
so obviously, what I will do is to inster a new layer which is 100 pixels high and 400 pixels wide (this is for the border to be covered by the wings
notice that it will appear in the top, and it won't move no mater what you do, well, the thing is that the GIMP does not allow you to move layers unless there is actually something in them.... so the trick is to paint it, move it and then clean it (remember, Ctrl+K)
2,3. I cleaned some more images and I will added them in the same procedure that I used to add Dart, and lowered the transparency level of them (to be barely visible)
4. of course that I will add another background, so I got some cool image in google and selected it, and as expected I pasted it and sent it to the
bottom layer......
Now it is almost done
