Those are his two styles though. The shorter one is the bush bow and the other the Deerslayer model. The Deesrlayer style is a little more demanding of precision in having enough material to form the brush deflecting part effectively.
If you've sketched it out and visualized brace height correctly is should be OK.
My first try I over finessed the shaping and at correct brace height the string was floating off the groove by just a hair.
