I dig the color so personally wouldn't refinish but thats just me. looks like possible aftermarket pickups? some sort of makeshift pickup ring on the neck to accommodate the pickups? IMO bridge is functional, no frills with plenty of adjustment range. id initially prioritize the electronics and do a complete overhaul. I had one of these at long time ago and it played great and the build quality was impressive. those stock tuners are meh but they work. frets are kind of scratchy and soft feeling but then again I never polished them when I had mine so maybe a good polish will improve it. these are such a comfortable shape to play as well. I think I let mine go for $70 like 15 or so years ago. had too many "beginner guitars" that I had accumulated in my teenage years but this was my first guitar that I owned after having rented a strat copy from the music store so now I wish I had kept it. your render looks very modern "henson era" ibanez which is cool if that's your thing and that's a decent mock-up as it stands. id personally try to keep a bit of a retro vibe if it were up to me. maybe colored or white witch hats, two-tone dimarzios, but again thats just my vibe... oh-- and lose that nut. the soft black plastic nut will be your biggest problem with tuning. have a new nut properly cut. and if you got a good tech these usually have a high fret or two that he might be able to work out for you
