I reckon you've taken on too much too soon!

Why dont you start again on the BM, looks like you have the right ideas but not the know how to implement them....maybe start by doing one piece at a time, smooth the doors off first and aim to have them 100% and in primer before starting something else. I can see what your trying to achieve and that you've thought about what you want to do but you need to start at the bottom and work your way up the ladder as you build your skills.

I've started with my Focus WIP which had its own thread on here, all i've done so far is stripped the paint back and subtly modified a few bits and pieces, eventually as my list of skills mount up I can keep evolving it until I reach where I want to be with it. I'm at the stage where i've done the metalwork and am about to order some Milliput so I can start the next stage.

As said, take your time with your project, slowly and surely......remember the saying run before you walk?
