thats awesome, I wish I had an evil twin. when are you gonna take your other two bataleons out? my gf did the same thing this weekend too. I took her out and she was working greens her second day which I was impressed, still kind of leafing on the heel but she has to get used to it and comfortable before I push her any farther.
anyways just some things to keep in mind
1) dont put your weight on your backfoot, it may seem more natural to sit in the back seat when you get some speed, but especially toeside this will lift your nose and make your board accelerate uphill when you try to stop. so youll end up wiping out. keep both knees evenly bent and if your riding down hill "flatbased" which is actually slightly on edge try putting a little more weight forward
2) make sure you accentuate your heel/toe lift to keep from catching edges when your turn, it helps that you have a bataleon, but its not impossible to catch an edge, I know from experience
3) if your having any issues initiating turns, again especially toeside, I see alot of beginners just drop to their knees because they expect their board to turn when they lift their heels, you can speed up your turn initiation by turning your upper body slightly into the turn. you may spin around 180 which is normal, but when you get to your edge counter rotate a little to hold where you are.
4) linking your turns is a gradual process. it starts by relaxing your lead foot until your nose is facing down hill again. then relaxing your rear foot while raising your toe/heel of your front foot depending on your direction. always make sure your not getting ahead of yourself, you will immediately bury your edge in the snow and fall on your ass or face. take your time and the linking will come, Im glad to see you already said its working but just some things to practice.
5) when you get to carving realize the difference is balance and control. mostly beginners "speed check" which is kind of an edge slide, if you balance your weight and lean a little farther on your edge it will hold instead of slide creating a nice easy turn, this may seem a little wierd or uncomfortable at first because you dont de-accelerate but by lowering your elevated edge youll speed check again. just something to play with.
These are the most common things I see beginners having problems with. Ive been teaching for two seasons now and am commonly asked what carving is, so I thought Id give a quick tutorial. try some of these out but dont take them as gospel, everyone is different and have their own style. so if this stuff doesnt work for you dont worry about it the rest will come. its always good to see someone with your enthusiasm when they start, stick with it and I bet youll be hittin the jumps maybe rails next year
