Great job on that green exotic man. I like your overall set-up too. Makes me wanna post the shop I've been working on over the past month. A few things that might help:

Punties - If your having trouble with cold seals, make sure that your heating and sealing as small of a surface area of your punty as you can. This can really be helped by rounding or tapering your punties before using them. An L marver does an awesome job of doing this for you. I had cold seal trouble at first, but watching these two things really helped me out.

Color - Dark Multi was one of the first colors i ever used. I recently used a couple of regular multi sticks, and didn't like it as much. Just my opinion. My current NS favorites are butterscotch and Amber Purple.

Fuming - Try playing with doing layers of Silver, and Gold. Also fuming Silver, burning it off, then using a reducing flame to bring it back can be fun, if you haven't ever tried it.

Repped for the awesome work, keep posting it man!
