Basically any tuto from the web when we are starting to make this kind of works, to make the burst as you called fire and brushWork tutos can help you just search any site for tutos on photoshop and sometimes you can even add the burst/brushwork in the 3D program_ thnaks for the support and take care
the atmosphere is very great. and you did a very good job on lightning and brushing. i like the liquid flow of your render very much. the only thing i dont like is the 2d.. i know you could do it better its to massive imo.
