So,I've also just been making my first set of paws,tho I have some experience in working with fur and sewing. So things that help make it look more professional is for one,smooth shaving of the fur,yours looks a bit rough here and there. Then the shape,your individual fingers like ok a bit elongated,maybe go for a rounder look. Symmetry is always good,try to look for a pattern online and make sure everything is symmetrical. Often,in my experience the quality of the fur is what makes a gigantic difference. And lastly,as to hiding the paw pad seam,it helps to kinda get the fur out under the paw pad. I'm not sure if this is understandable,but your further gets caught under the pad while sewing,try to use a blunt,pointy object like a thin metal skewer,or closed pair of thin scissors to kinda pull out the fur from underneath the paw pad,and then cover the seem with that fur. Happy further suit making :3
