I definitely can do that. I will break it down into a list!
Skill Level: Minimal (I have done 0 models)
Accuracy and Detail: What I mean by this is replicating real life cars as closely as possible without going into modding of bodies etc. Simply paint and decals.
6 Month Goals: To be able to construct and paint/decal a life like 1:24th replica car to decent detail (decent: paint will have probable marks/scuffs, decals will not be straight, engine and accessories might not be perfect)
12 Month Goals: To be able to construct and paint/decal a life like 1:24th replica car to great detail (great: paint will be near flawless, decals will be straight, engine and accessories paints to detail)
I know this is still very bland but it is something.
