hi again! i don't use ibispaint, no. me personally, since i draw i already had these, i use clip studio paint & paint tool SAI. any free art program would work though. for gradients, i personally use photopea or yoksel's SVG gradient map

to be honest i myself am quite new at this as well so i wouldn't say i'm the best person to go to for advice, but i made the gradient the images on my neospring have here using yoksel's gradient map site.
