My first build, tips please.

I attempted my first build this morning. The one question I have right now that someone could help me with is did I use enough cotton? As far as the wire gauge I forgot what my son told me when he dropped it off and I cant read the label. It is reading 0.7 ohms and wrapped 6 times. Sorry I am not as detailed as some descriptions. I will take any tips, one is I know I should spend more than 5 min doing these, Thanks in advance
