Well for a new player, its not bad.

IDK what kind of success you have in game, but one thing you need to know is Ashe is squishy. This means that even though she does great dmg, she doesnt live long if someone gets close to her. Most melee champs will eat you alive.

Your runes are great. You want as much dmg as you can get. Dont change them at anytime. Assuming you have a low summoner lvl, you will want to upgrade your runes as you lvl. If you have filled your rune book with the tier of runes you can use, start saving for the next tier lvl. Or start saving and buying tier 3 runes. Either way, the ArP and Crit dmg runes you have are great for getting the max dmg you are wanting.

Masteries are great too. The thing about good hands is you spend less time dead. That is good sometimes. If you are needing to push, you will come back sooner. Same for Defending. If your low death time means you can defend a push, than its good. Its a personal choice. Overall, great Masteries.

Skills. Personally I dont like when players have expensive builds, but dont use Hawk Shot will late game. This is bad. I agree with ECA>Volley, but you dont need alot of FS early game. One rank is good enough for the early-mid game. Hawk Shot is better to lvl in my opinion. Not only can you gain extra gold from kills, the scouting area shown is increased. That is helpful when scouting the various buffs in what ever zone you are in.

I would take one Phantom Dancer out and get something like Banshee's Vale. This will add to your survival rate. Or you could get something that will increase your health. Frozen Mallet will good for that. And eliminates the use of FS. If you want to go Hardcore on life, get Warmonger's Armor. This is great for life.

These are just my opinion. If you dont like them, you dont have to try them
