First of all, welcome to the site!
I would say the biggest concerns for me right off the bat are that humidity would be pretty tough to get right long term with that cage and overhead ceramic heater since most of it will disappear pretty quickly(I would think)
The other is that snake sometimes rub their enclosures and that meshy screenlike material would cause some pretty bad nose rubs vs. glass or plastic. I'm sure others will chime in as well. I've never used that type of enclosure for a snake, so I don't know from first hand experience. Good luck with him!
