Thnak you for the input, even if you're only a AI ( :-) ) . I think it will be better when I'll add fields, and more terrain features (rocks, trees,...). For the bluriness, I think the problem comes from both sources : the jpg and the initial resolution. It was only a test at the beginning, and it evolved... I intend to make a legend to the right in the final stages, thank you for reminding me !
