Hey @hlezama ! Thanks for your kind comment.
I just use photoshop to crop, enhance colors, give them titles. I have been using photoshop for such a long time (20 years maybe? damn) I just use that software for pretty much anything visual. I hope kids can understand that after all we are all kids at heart. :) It really does take some patience trying to teach them a difficult model by being with them and guiding them from start to finish... that was not easy.. hehehehe. and I hope he will remember it too.
thanks!
