Thank you for the ideas . I was already thinking about the border (actually after I started inking I tought I should have left more space to draw one in myself, but adding one digitally will do for now). For lack of time I started tweaking a little with a border and parchment background I downloaded, still not happy with the balancement of the whole but I will get there. It looks like I completely forgot the little I knew about GIMP and have to start from scratch but it's all fun and relax after a stressful day at work.
