As countryscroller said, a bit of practice and your cuts will become much smoother, but very nice work especially as it's your first projects.
What blades are you using? I had the devils own job trying to follow lines untill I switched to Flying Dutchman Blades. My cutting improved instantly with those blades. I mainly use FD UR #1 and #3 blades and not only do they cut nicely, they leave almost no fuzzies to sand off. As every 3rd tooth is reversed it cuts on the up stroke as well as the down and the finish after cutting requires next to no sanding.
