Hey there! You are very skilled yourself! Your cuts are clean and perfect!
Generally, my process is to draw on the back of the paper and I design as I go, but here are some things I learned from experience.
1. Doing a rough sketch helps you visualise your idea better.
2. The paper density is important, too thin and you risk damaging it, too thick and your hands will be sore from having applying too much pressure when cutting.
3. When planning a design, try and make sure that composition-wise, parts are connected so that it won’t be too flimsy. A way to do that would be to have a ‘frame’.
4. If you are working with type/words, make sure it is mirrored (as I draw on the back of the paper)
5. Be flexible. If you make a small mistake, embrace it and find ways to work with/around it like tweaking the design just a little bit.
6. Rest occasionally. I would sometimes be caught working on a paper cut for hours without stopping and the result would be a hurt wrist (actually the pain spread to the shoulder) for months. This happened a few times until I realised I wasn’t superhuman and was over-working myself.
It always comes down to personal preference but I hope this helped! Will keep an eye on ya! :D
