very good start. I can't give you advice, I'm just learning also. Well I can pass on two pieces of advice that were given me and really helpful to me. 1 - take a deeo breath before starting to to cut and then concentrate on breathing normally. 2 - Lower your shoulders don't have then raised up around your ears. Simple advice, but really helped me. The main thing this advice was telling me was to relax.
Another thing I have done in buy many sizes and types of blades from Mike's Workshop and I have been experimenting with them to determine which ones work best for me on different types of cuts.
Between the deer and the duck you can already see improvement, so practice, practice. I'm accumulating quite a pile of practice cuttings. I wish I would have numbered them so I could see if I am improving.
