He reminds me of Ginger, my Belgian/TB cross mare. Similar kind of expression. He looks comfortable with you.
I wouldn't necessarily recommend this to anyone but you can do it, if you have enough guts and determination. I did it. I learned to ride and train horses on Ginger and we were both green. Bear in mind that it's true what they say though, green on green makes black and blue. It's a risk. I got beat up, thrown off the side, dragged by a stirrup, bucked off, and run off with but I refused to give up and today I've actually learned to be a horse trainer. But I studied, and I mean hard. I still study hard 7 days a week, and then go out and practice what I've studied. If you have it in you, I'm sure you can do it too. It takes a long time though, and this horse is what we call your 'sacrificial lamb'. You're going to make all your rookie mistakes with him and he'll have to bear the burden of your lack of experience. Still, it's better than the kill truck imo.
If I could go back in time and tell myself a few key things they would be these.
1. Having control of the hindquarters will save your life.
2. The best way to get better at riding is to actually ride.
3. The more you learn, the less you know.
4. You're going to screw up, a LOT. Don't worry so much about it. It's all just part of learning. Horsemanship is a journey not a destination, so may as well enjoy it.
Finally, the only way to get good at this stuff is to have a strong desire and determination to come back and try again and again. Trust your instincts though. You don't have to get in over your head and get into situations where you'll get hurt, though it might happen at times. Just do what you're comfortable with doing, and the things you can do will increase over time as you get better and better.
