Before Remi beats me to it.
Some non-Dan moves from my kyu perspective:

No way. You got a weak group on the bottom and you're inviting a splitting attack. As white I consider

sente (well, sente moves are ones that you hope the opponent ignores, but here as black I never know how to proceed if white ignores..). Furthermore, playing an unsupported approach against a shimari is very desparate, if not a no go. Moving halfway to r10 offsetting the influence of the shimari, looks better to me, if you are going to tenuki.

Entering sansan wrecks the outside. Bad exchange in this instance. Say thank you.

Even here, I think q18 is still possible as his corner is gonna die first if he cuts. Now your two walls on the right hand size are offset by his group which looks hard to attack severely. Didn't go well.

I don't like the kick. WIth the open skirt on top, his stone will get really easy life. A counterindication is also that he can make an ideal extension. The kick would be better if there were a friendliy stone on k16, because black gets overconcentrated.

Unprovoked headbutting. The start of the avalanche is the only one I consider kosher. And even that one demands some caution.

I agree that it is a shape move for your opponent. But now you invite a familiy feud on bottom and top. If black plays naturally, something of yours is going to die.
:w126: better wait. There is a cutting point on m10, and it might be beneficial to have an extra liberty. Later s7 is going to be a good endgame.
:w148: I don't think you saw the tombstone squeeze. Neither did your opponent. It won't turn the tables but the sudden appearance of fear in the face of the opponent should be reward enough to do it anyway.
