My generator needs to work better

If you use to many dolls or text the images won't print right. They will if you use only one doll and less text. [login to view URL] Examples This is a good correct image [login to view URL] This is a bad image using to many dolls, and I used the same letter text as above, Notice how the one doll blinks and it shouldn't and the text changed to a black color. [login to view URL] Also is there a way to make the text space? Instead of testtest have it go like test test? This is not as important, but can it be made to have a bigger text box so the text can be made to do this Have a Nice Day Instead of Have a Nice Day? I can't afford alot. Thankyou.
