I like that your build isn't the typical sniper. That's admirable but WOW... a TON of points going to Cmans. It's not a bad thing, but can also be a later level goal.
Going ranged you may as well get your ambush up to 2x. At your current level you'll start to get AS benefits from it. If possible, pickup at least one rank of Summoning and one rank of Blessings. According to the Whirlin guide that's all you should do until you've got the rest of your training where you want it.
S&H may as well be either 2x or 1x IMO. 2x and hide from most everything, stay in hiding and snipe. 1x and hide from everything but undead and animals.
Have you thought of getting your armor to at least 30 for brig right now, then pumping up CMAN's later while not training armor? More Dodge is never bad and you're already looking into some MIU and AS. I suppose you'll want some of that though I've found I never use scrolls and the only magic items I end up using are small statues so I can't give much advice about getting those skills.
Stats are tough. RT is so STR dependent I ended up hitting 100's in STR, AGI and DEX by like level 40. Now I'll have to pay for a fixstats or grind bounties. I'd say to do what you can to at least shoot a composite bow aimed in 5 seconds. Other than that, set for as high as you can.
