Hi there, another elven rigger at your service.
First of, attributes look ok, nothing I'd realy change there.
2nd; Skills. I'd bumpt Electronic Warfare up to max. It's a bad day when your drones start falling out of the sky due to enemy hackers. I'd also put some points into etiquette.
3rd; the fun stuff, weapons, vehicles and drones.
Bulldog and mirage: Get morphing license plates and spoof chips. Everyone should have these on their vehicles. You can run bogus plates while on a job etc, it's great.
Roto-Drone: Why chameleon coating on that one? It's 30k ish nuyen on a fairly squishy peice of equipment. I'd also pick up a few more fly-spys, those things are great.
Autosofts for targeting is bought on a wepon basis, for example, your Autosoft (Steel Lynx Targeting) would me a Stoner ARES targeting autosoft. Speaking of the stoner, I'd probably replace it with a Krime Wave, would save ou a couple of thousand nuyen.
I'd also add a hot sim to whatever for the increased initiative when you rigg in.
regarding the tool shop, I think you need to specify what kind of shop it is (Drone repairs, autoshop etc).
Other than that, I can't realy find anything else on the sheet.
Tips for reading, apart from the whole rigger chapter and parts of the trix in core. Back when I got into the hib, /u/eljakob737 (I tihnk at least) posted a link to this, a collection of rules summaries, I highly recomend having the rigger one pulled up whenever you're playing. It's a lot of things to remember, but it's a fun archetype.
Oh, and since I'm not a sheet checker, I'll just leave everything up to them.
