Hey man,I hope you take this the right way as intended, my biggest recommendation is to start small and work up, you learn faster that way, you've got good ideas and in time the execution will come and then it'll be epic! But right now I'd start by doing less, maybe a wheel change, lowering and tinted windows, nail it, then work your way up and when you get there, then go crazy!

also another way to learn fast and iron out little flaws is to post in the wip section and see what faults people pick up on and also to get advice on atuff! Keep up the good work bro!
