Howdy! Welcome to the forums. Definitely get that basking light replaced - the heat should be between 80-85 degrees for basking.
As far as a tilted head, that *can* indicate a respiratory infection, but usually there are other signs. What is your humidity during the day? If he's also got stringy saliva, sleeping with his nose up at night, any sort of popping/crackling sounds or odd behavior, that can also indicate it.
Without context, the pose that you've posted there seems normal to me, as my guy will push up on his front legs especially when he's hunting black soldier flies bouncing around his enclosure. But if you're seeing any combo of the above things, it may be worth concern.
If you'd like, you can fill out the husbandry form and we can review the overall look at your chameleon care. That can help us determine if there's anything that might be off, and could be causal in what concerning behaviors you might be seeing. If you're interested in filling one out, copy and paste the below in a reply here and we can review it!
