Hi and welcome to the crazy world of customizing. The goal I guess is to be able to be a really great sculptor. I want to make a successful mold and cast. Once I make a mold, I can then sell replicas in resin...which will give me more ca$h to fund my expen$ive hobbie$. I will shrink a select few of them to Mego scale...but again that needs more chimpchange.
You will not believe this, but I have downsized my sculpting tools. I use an exacto knife, a wooden toothpick (one end is blunt and sanded smooth--the other end is just left sharp), a medium sized paint brush and 99% isopropyl alcohol (for smoothing down the sculpts), and a box of sculpey firm. That's it. And also the will to make it so.
You just have to start. It will look like crap at first, but you get better with each successive sculpt.
