I don't see anything wrong/undesirable about your previous pics. They seem pretty good/clear. You've posted plenty for us to get a very good idea of what you've got. Thanks.
There are so many different colors to wood types esp. mahogany. I've made lots of guitars with mahogany that range from very light yellowish (even more yellow and lighter than yours) to very dark reddish brown. Most of them have a distinct iridescence when finished with gloss lacquer. Another very similar wood in just about every respect is Sapele, which I've also used alot and actually prefer over mahogany for a number of reasons.
It's near impossible to identify the exact type of mahogany (or Sapele) from just a photo, but it is safe to assume that this IS a type of mahogany.
While separate slabs of the same type of wood can share some basic tonal characteristics with its relatives, keep in mind that each piece will have its unique tone...even two slabs from the same tree. However, this is minor since the electronics (pickups, amplifier, speakers) and hardware are together responsible for about 75-95% of your guitar's tone with wood being responsible for only about 10-15%. The neck is probably responsible for 45-70% of the guitar's tone attributable to the wood. Typically, mahogany will have a warm, very full tone, especially when compared to maple. Your guitar has body and neck out of mahogany and a rosewood fretboard (which also is a warm sounding wood) so I'd suspect that it will have a very warm, full tone. Sometimes that can also mean that it won't have "snap" and definition/articulation and can be a bit bassy and even "muddy" sounding. This is the reason why many guitars (like typical Les Pauls) will have a maple cap on their mahogany bodies.
So, are you going to complete this project? Good luck. Let us know if you need/want any help along the way. Going with Strat single coil pups or humbuckers? Or better yet,
p-90s?
In any case, I would suggest that you start with some bright pickups.
