Some crits here. Panel 1 close the guard. That open guard will get passed very easily. The arrows in panel 1 are ok but putting another panel in between panel 1 and 2 of the arms being opened will help explain this better I think. From my experience you want to kick up as you pull the arms open. Not open them then bring the legs up. Also going into some technique here on panel 4 explaining "thumb up" for an armbar might be good here. Right now the illustration looks like the technique will not work the way its set up. Maybe the art in panel 5 could be a small inset for panel 2. The other issue I have is why does this end in an armbar at all when the title is triangle lock from guard (Triangle choke might be better)?.
The ground martial arts game is still very new to me. I only managed to capture part of what was shown in class that day. There were several transitions from the triangle which were demonstrated, but I didn't really get all of what was demonstrated.
Haha, as a thumbnail and before reading the description I thought these were kama sutra type illustrations
That's not very helpful is it?
In a more serious crit, these seem like very safe angles to me, if it's appropriate for the client's needs (which could also be a teacher or yourself) you might try more extreme perspective such as going over the shoulder of the assailant, busting out the fish eye lens, etc.
