Hi Finnegan,
I will give you some advice in regards to your striking since that is my what I do (boxing). If some of my points don't make sense for MMA then just ignore them:
1. Look at the little tusle' at 1:56. You pulled your head back when throwing which is a common mistake that is hard as fuck to correct. Never do this as you are prone to overhand rights. Keep that chin tucked! Your opponent was doing this as well. If you notice this from now on then throw a few jab feints and then come over the top with the over hand right.
2. I liked it very much from about 2:01 to 2:10 when you scored that knockdown. See what happens when you come in behind the jab? You established the distance well with the jab and came in with a BEAUTIFUL straight right.
3. I would try starting more off the jab with your combinations. This might not be optimal in MMA but look how you got taken down at 3:13. A few good hard jabs and THEN the leg kick would have been more effective since he would of had to back up and wouldn't of had the time to even think about taking you down. I would try that in training. A few HARD jabs and then a hard leg kick. Could be a devastating combination with your size. Also, at 3:54 you throwed a hook (looked like) before going into the clinch. A good counter uppercut or check hook would have levelled you. I wouldn't start off a combo with that. Maybe throw a feint jab ad then a hook. Jabs really put your opponent off balance and make them lose their focus. Use them a lot more.
4. Use your range a little more, as well. Try not to get TOO close to him. You will essentially smother your power. From 4:10 to 4:25 is a good example. You don't need to be in close to land them big right hands. Watch this video of Kelly pavlik-
http://www.youtube.com/watch?v=HchCpnORAqk . Watch his fights if you can. He uses his range very well. If you do get in close then throw more 'tight' uppercuts (the crowd was yellin out uppercuts as well).When in close you can standmore sideways and use your shoulder as a defensive barrier and can conceal your hooks more. If you have seen Floyd Mayweather fight then you will know what I mean.
5. Some more body punches would have been good as well. Mix up your attack.
Overall, you were impressive. A little more work on your punching technique and defense and you will be a powerful force. Combining excellent boxing skills and defense (bobbing, slipping, weaving), along with the strength of your clinch and ground game and you will go along way.
Hope this helps
