Yes you right, you should quit immediately and move to New Zealand, onto a farm, looking after sheep...lol... We have all been down this road and i have quit many times!! In fact i recall booting my PC out the window and taking up the same scene that drove me insane the following morning. The thing that i always tell my staff is that you guys are living in the wonderful age of internet, forums and online tutorials. When i started this insane profession there was nothing except experimenting, breaking things, crashing things and somewhere in between bad coffee. There were very few people that new what they were doing and i did not know any of them. Getting back to you and problems at hand. I think guys above me pretty much have covered it all about composition, materials, vray settings and so on... What i would advice is maybe to just hold out on Grant Warwick's stuff for a little while because i think you will find him fairly overwhelming at this point. As much as i have respect for Grant i think he takes it to the next level right from the beginning. My advice would be to get your solid foundations established. It is not about watching hundreds of tutorials. It is about watching the correct tutorials by guys who have actually produced something for the industry and know what it takes to do it in a studio environment. Anything is possible if you spend enough time on it, but can you do it in 48 hours and make sure that quality is banging? So i would say start with "viscorbel". He is great in explaining and reasoning out why he does it in a way that he does and when it comes to modelling he is the man!!! Literally!!! All my guys have been put through his tutorials and it is a great foundation that can be build on. That is my two minutes of rambling and do not give up!!! Rome was not build in a day.... but we can (in max)....lol... Best of luck and let us know on your progress....
