Armbar: Nice progress Timmy you've definitely got the set up right now its just about perfecting the little details. I'd say that leg hook that goes around the head is the most important step and the most difficult because the leg has to make that big arc over uke's head and then cut back and snap down on it.
Once you get that hook you are have really 'locked' up the position + big damage bonus + that hip will provide leverage to break uke's arm provided that the arm is in the correct position. So definitely focus on perfecting that step.
Side Kick: monkeyishi i like your input. And yes i agree pulling guard or a direct turnover is a sneaky follow up to kicks. And leg kicks are another move i wanted to get into. I like leg kicks a lot because they're very low risk which a chance of high reward. Even if the kick provides no dm or frac the follow up transition is very smooth so its great to start a combination technique.
