Rate my play: the Mongol Raiding scenario

Full disclosure: I am not a very good player, heck I have yet to even play online. I do want to improve myself though, and one day I might be able to go online

How I played it:

1. Yellow: I queued 5 Trebs and a number of vils, then use Subotai and the 14 Mangudais to defend the trebs. Yellow's Castle went down by 2 Trebs when the third were out, and my vil count is 10 jacks + 8 farmers + 10+3 miners + 6 shepherds
2. Purple: I used all 5 Trebs to target Purple's Castle, now using all the starting units to defend 'em. At the starting Castle I upgraded to Elite Magudai and queued them indefinitely, also grabbing Bracer and Parthian Tactics. 6 shepherds, once done with the pigs, are then sent south to build a Castle
3. Orange: 5 Trebs v. Castle again. I continued building Castles after the second, which was used to make 5 more Trebs before transitioning to Mangudais
4. Teal: I sniped the Towers first (in retrospect, this was the most time-consuming part) while waitng for new Mangudais to be made from every Castle I own. Once I had 10 Trebs then I sent 'em to snipe the Monastery, with Mangudais providing cover fire
5. Grey: I queued up several Demo Ships and sent 'em forward to deal with the Galleons. Then it's 10 Trebs v. TC, with Mangudais fending off Paladins and Huszars.
6. Red: I had about 20 years left, so I just Shift-click the Trebs to take out the south Castle first, the Wonder second, and I had all the Mangudais be meat-shields against TKnights and Paladins. The Wonder came down with 2-3 years remaining and I got 29k

Hindsight thoughts:

1. I probably can make room for Steppes as well, but I got caught up with moving waypoints and wasn't quick enough in my macro to create a big enough army
2. I could make a pincer to go after Red with, since I completely neglected the north passage and Mangudais moving north to south was quite time-consuming. Again, no macro skills :(
3. I'm wondering if I have to destroy all Towers before going after Teal's Monastery
