Yes, I would make ventilation under the arms and in the back, its way too hot to wear for more than an hour or so. I would also use a different paint and put a durable clear coat over the top of it because sweat or water causes the paint to run. Lastly I would like to make my own mask as the mask I used was a bit small in size compared to the hulk body I built. I have never done a latex mask before though and I don't have the time to learn how to right now. If anyone has a good video tutorial on making a latex mask that they could share with me I would appreciate it.
