Just some questions:

How old should the kids be?

Would you prefer a photographic cover or a more graphical/illustrated one?

Did I get you right ... you only need an electronic version - or will the cover be printed as well?

Thanks for your great question. The kids should be about 5 years old. I prefer it to be illustrated. Right now I''m only releasing the book electronically, however, it would be good to have a printed version too if I need it later. Thanks.

I just want to ask, what I must draw is front and back cover, or just the front one?
if both of them, so what description must I write down behind?
Thank you

Just the front. It will be an e-book to start. Thank you.

what dimensions will the cover be
