10: It seems ok to me. It attacks a stone, it works well on a large scale with D16 and K16, and it prepares invasion/reduction in the lower right.
Keep in mind that you are commiting yourself to fighting on a large scale. ( For comparison, you could play C6, which in more territorial. )
At kyu level, it is not so important that you play the absolutely best move, but rather that you play a good move AND you know what it means.
12: I tend to agree with your choice. But we both could be wrong.
16: This is big, but slow and gote. It seems locally good, but on a large scale it ignores the high white stones up top. I would have played D6 out of respect for those stones.
18: This is not a good move. It ignores the meaning of the previous moves. Very locally it looks ok, for it probably kills a stone. But seen on a slightly larger scale - the corner -it conflicts with C2. If C2 is what you want to do, then to be consistent you must follow it up with D2.
On yet a larger scale, G5 is inconsistent with the idea of J4. It cashes in too soon. Again, D6 seems thematic when looking at the whole board.
You are not making really bad moves, but inconsistent ones - moves that ignore the meaning of their predecessors.
37: "Hushfield: I have some connection issues, should I drop from the game, i'll try to reconnect as soon as possible"
Good pun!
