The shadows near the bottom of the pic need to be more blackish rather than grayish. (That part near the brown whatchamacallit.) Looks good otherwise.
Yeah.... Upper strings need a bronze tone and the bottom need silver. Other than that it looks good. Wayyy too long of a load though.
Guitar strings don't usually have colour. Not on my guitar anyways. Sorry for the size it takes like 2 secs to load on my pc.
Yeah some guitars have copper other might have some different coating like a nickel coated string, but how ever you want sounds good. About the loading, yeah 2 seconds sounds about right lol.
The spoilers help load but they don't resize... Can't see the whole thing in a spoiler w/o scrolling all around. Just embedded was better.
