I was very good at Photoshop long time ago and now I am more on the open source side of the street. Gimp has been a nightmare for years but today well...! even without a mouse I could make this silly edition of a beach day! Thank you Rebecca!
I only noticed that when rotating/using perspective, the quality of the image drastically decreases. I found out that this has been reported by other Gimp users so the best in their opinion is to resize the image after the rotations. I was too lazy to start again for this one, and I learned SO MUCH!
