Welcome to the site & the casting disease, for which there is no cure!
Nice boolets on your first try. Far better results than I had when I first started.
Above all else, THINK SAFETY! You're only given 1 pair of eyes, so take heed. Pb & H2O don't mix! Don't let water get near your work area.
This hobby is a constant learning experience, always new skills to discover. You're off to a good start.
