Well...I've look at your portfolio, and I think you still have a lot of room for improvement. I can see you have potential, but your stuff aren't quite meet with the industry standard yet.
The CG industry is a lot harder to break-in than couple years ago, people can learn a lot of stuff just by all the online tutorial and forums, thus it raise the bar even higher. Just put yourself into their shoes, will you hire someone that need to be train or hire someone who is good already? You can't expect the company pay to train you right?
Trust me, age isn't a problem at all, the only way to break into the industry is keep trying. If your current demo reel can't get you a job, you have to figure out the problem and redo your demo reel. I know it's not easy to come up with another demo reel, it require so much time, energy, and patient, this is the only way you can break through however.
It took me 1 and half year to get a job after I graduated. What happen is, it took me three months to work on my first demo reel, and then I sent it out to over 100 companies, but got no response at all, so I used another six months to build my second demo reel while working full time as an regular office boy (I still need to pay my rent

) This time I got two interviews, but still no luck. I was very frustrated that I almost going to give up. But I pull myself together and spent another 9 months to work on my reel, and finally I got my first CG job!!
It may be hard to get into the CG industry, you will feel tired, frustration, disappoinment, anxious~~~etc, but the fruit of success is even sweeter after all the hard work, so don't give up and keep trying!!
